摘要：
lsospin symmetry is expected for the T, = 1 -> 0 isobaric analogous transitions in isobars with mass number A, where T-z 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 T-z = + 1 -> 0, 50Cr(He-3,t)Mn-50 study at 0 degrees in combination with the decay Q-value and lifetime from the T-z = -1 -> 0 Fe-50 -> Mn-50 beta decay. This method can be applied to other pf-shell nuclei and can be used to study GT strengths of astrophysical interest.
