Measurement of Gamow-Teller Strength via (t,^3He)
Abstract
Electron capture and beta decay play important roles in the evolution of pre-supernovae stars and their collapse. Recent predictions for weak interactions in modern large-scale shell model calculations that include residual interactions differ greatly from earlier rates determined from independent particle models. We report preliminary results for the measurement of the GT strength in ^58Co via the ^58Ni(t,^3He) reaction with a secondary triton beam of intensity ∼10^6pps at 112 MeV/nucleon. In preparation for future (t,^3He) measurements, we have performed test experiments that demonstrate enhancements in the triton beam intensity by an order of magnitude to ∼10^7pps.
