Gamow-Teller Strengths from (t,3He) Charge Exchange Experiments

ORAL

Abstract

In pre-collapse and post-bounce evolutionary stages of massive stars, electrons have energies high enough to excite Gamow-Teller (GT) resonances. GT-Strengths are important inputs for codes modeling the dynamics of supernovae. To validate theoretical estimates for GT-Strength distribution, detailed comparisons with experimental results are important. Charge exchange experiments fill this demand. Preliminary results of a recent (t,3He) experiment run at the National Superconducting Cyclotron Laboratory on CD2, 24Mg, 63Cu, 94Mo targets are presented, including a brief discussion of models used to calculate GT strengths.
