Internal conversion is also the predominant mode of de-excitation whenever the initial and final spin states are the same ( but with other different quantum numbers ); however the multi-polarity rules for non-zero initial and final spin states do not necessarily forbid the competing de-excitation by emission of a gamma ray in such cases.
