Abstract

Recently the measurement of γ-transitions to and from isobaric analogue states has become an important tool for studying nuclear structure. In order to obtain information on the corresponding β-decays from these experiments for heavier nuclei, we must estimate possible theoretical corrections carefully. In this paper the previous formalism for isobaric analogue states is extended to cases including E1 γ-transitions, and it is shown that the correction terms are small for the Pb region, but it is dangerous to believe that they are small for all nuclei.
