Scientific paper

It is suggested that the production of technetium in red giant stars is not necessarily related to an interior s-process mechanism. Red giant spectra with technetium lines are examined, showing that the correlation between metallicity and technetium production in the spectra is the opposite of that which is expected from an s-process. It is found that observations of technetium in metal-rich (population I) red giants might be explained by gamma-ray-induced fission of heavy isotopes initially present in the stellar envelope.
