Abstract

Isospin symmetry is expected for the Tz=±1→0 isobaric analogous transitions in isobars with mass number A, where Tz is the z component of isospin T. Assuming this symmetry, strengths of analogous Gamow-Teller (GT) transitions within A=50 isobars were determined from a high energy-resolution Tz=+1→0, Cr50(He3,t)Mn50 study at 0° in combination with the decay Q value and lifetime from the Tz=-1→0, Fe50→Mn50 βdecay. This method can be applied to other pf-shell nuclei and can be used to study GT strengths of astrophysical interest.
