The two groups are Emanuel Maxwell, who published his results in Isotope Effect in the Superconductivity of Mercury and C. A. Reynolds, B. Serin, W. H. Wright, and L. B. Nesbitt who published their results 10 pages later in Superconductivity of Isotopes of Mercury.

Isotopes are atoms of the same element ( that is, with the same number of protons in their atomic nucleus ), but having different numbers of neutrons.

Isotopes are distinguished by the atomic mass number ( total protons and neutrons ) for a particular isotope of an element, with this number combined with the pertinent element's symbol.

The least stable is < sup > 138 </ sup > Dy with a half-life of 200 ms. Isotopes that are lighter than the stable isotopes tend to decay primarily by β < sup >+</ sup > decay, while those that are heavier tend to decay by β < sup >−</ sup > decay, with some exceptions.

Isotopes of other elements are not so great a problem as they can be removed by chemical means.

Isotopes of unbinilium are predicted to have alpha decay half-lives of the order of microseconds.

Isotopes are often preferentially absorbed by biologically active tissue in the body, and can be used to identify tumors or fracture points in bone.

Isotopes with gaseous precursors solidify on the surface of the particles as they are produced by decay.

Isotopes and Mass-spectra and Isotopes are his most well-known books.

* Isotopes are nuclides having the same number of protons ; e. g. carbon-12 and carbon-13.

The other divisions and technical groups are: Accelerator Applications, Aerospace Nuclear Science & Technology Technical Group, Biology and Medicine, Computational Medical Physics Working Group, Decommissioning, Decontamination & Reutilization, Education and Training, Environmental Sciences, Fuel Cycle and Waste Management ; Fusion Energy ; Human Factors ; Isotopes and Radiation ; Materials Science and Technology ; Mathematics and Computation, Nuclear Criticality Safety ; Nuclear Installations Safety, Operations and Power ; Radiation Protection and Shielding ; Reactor Physics ; Robotics and Remote Systems ; and Thermal hydraulics.

The crowd then takes notice that the hot dogs are even wrapped with " Albuquerque Isotopes " paper and are enraged.

Months later, he enters Moe's Tavern and is informed by Lenny and Carl that the Isotopes are in the playoffs, and have, so far, been playing well.

Isotopes are forms of the same element that have variable numbers of neutrons in their nuclei.

Isotopes of samarium are used in samarium-neodymium dating for determining the age relationships of rocks and meteorites.

Isotopes with atomic masses lower than the most abundant stable isotope, < sup > 158 </ sup > Gd, primarily decay via electron capture to Eu ( europium ) isotopes.

Isotopes heavier than < sup > 62 </ sup > Ni cannot be formed by nuclear fusion without losing energy.

Isotopes of silver range in relative atomic mass from 93. 943 (< sup > 94 </ sup > Ag ) to 126. 936 (< sup > 127 </ sup > Ag ); the primary decay mode before the most abundant stable isotope, < sup > 107 </ sup > Ag, is electron capture and the primary mode after is beta decay.

Isotopes with a mass number above 64 decay by β < sup >-</ sup >, whereas those with a mass number below 64 decay by β < sup >+</ sup >.

Also, the ratio of < sup > 15 </ sup > N /< sup > 14 </ sup > N in an organism can give clues about its diet, as movement up the food chain tends to concentrate the < sup > 15 </ sup > N isotope, by 3-4 ‰ with each step of the food chain-see Isotopic signatures-Nitrogen Isotopes.

The radioactive but long-lived Ho-166m1 ( see " Isotopes " above ) is used in calibration of gamma ray spectrometers .< ref >

Isotopes of silver range in atomic weight from 92. 950 u (< sup > 93 </ sup > Ag ) to 129. 950 u (< sup > 130 </ sup > Ag ).

Isotopes of bohrium have also been detected in the decay of heavier elements.

Isotopes which undergo this decay and thereby emit positrons include carbon-11, potassium-40, nitrogen-13, oxygen-15, fluorine-18, and iodine-121.

Isotopes with significant branching of decay modes include copper-64, arsenic-74, rhodium-102, indium-112, iodine-126 and holmium-164.

Isotopes of Carbon, Oxygen, and Nitrogen can be purified by chilling these gases or compounds nearly to their liquification temperature in very tall columns ( 200 to 700 feet tall — 70 to 200 meters ).

As NASA's first all-atomic powered spacecraft, these used plutonium-238 units developed by Teledyne Isotopes.

A group headed by Ken Young, who is president of Ovations Food Service and also the owner of the Norfolk Tides, the Triple-A affiliate of the Baltimore Orioles and the Albuquerque Isotopes, the Triple-A affiliate of the Florida Marlins.

Skinner ), Nuclear Physics ( initially headed by Otto Frisch, later E. Bretscher ), Reactor Physics ( John Dunworth ), Theoretical Physics ( Klaus Fuchs, later Brian Flowers ), Isotopes ( Henry Seligmann ) and Engineering ( Harold Tongue, later Robert Jackson ).

Fans of The Simpsons may also recognize Keach's voice in the recurring role of Duff Brewery President, Howard K. Duff VIII, beginning with the 12th season episode, " Hungry, Hungry Homer ", wherein Homer attempts to stop Howard K. Duff from moving the Springfield Isotopes baseball team to Albuquerque by staging a hunger strike.

On May 16, he was released by the Mets and he signed with the Los Angeles Dodgers on June 10 and was assigned to the AAA Albuquerque Isotopes.

Homer is offered the job as team mascot of the Springfield Isotopes by the team's owner.

When he tries to help Lenny by getting him a refund on his tickets for the Springfield Isotopes, Homer encounters the Isotopes ' owner Howard K. Duff VIII.

After the first pitch Homer, becoming increasingly annoyed by the poor performance of the Isotopes, goes and waits in the car.

Neither the opening with The Isotopes nor the finale with the rather dire song help this one at all, and frankly, if it wasn't for the superb parody of Village of the Damned, and the kids ' revenge by revealing their family's secrets, it'd sink without trace.

When they sell candy in the hope of becoming batboys at a Springfield Isotopes game, the " Pre-Teen Braves " try to thwart the " Cavalry Kids " by lacing their candy bars with laxatives.

He was signed to a minor league contract by the Los Angeles Dodgers on June 23, 2010 and assigned to the AAA Albuquerque Isotopes.

However, Isotopes management scrapped those plans due to security concerns and instead converted it into a play area for children.

* Isotopes that undergo Beta emission transmute from one element to another element, those that undergo gamma or X-ray emission don't change in element or isotope.
