1 Measurement of 58 Co Gamow-Teller Strength via (t, 3 He) Arthur L. Cole National Superconducting Cyclotron Laboratory, Michigan State University ref: ESA

2 Motivation: Electron Capture WW: Woosley, Weaver (FFN) w/ Independent Particle Model LMP: Langanke, Martinez-Pinedo; Heger, Langanke w/ Shell Model Independent Particle Model (IPM) Shell Model (SM) protons neutrons f 7/2 f 5/2 protons neutrons Need Experiment to test and validate model calculations Example: 56 Ni 28+  56 Co 27+ Heger et al. (2001) Core Collapse Supernovae, Pre-collapse Stage: EC influences pressure, entropy, electron fraction (Y e )

3 Gamow-Teller Strength, B(GT) Study Electron Capture: e - + 58 Ni  58 Co + via Charge-Exchange : t + 58 Ni  58 Co + 3 He Fujiwara et al. (1996) ( 3 He,t) Linearity Gamow-Teller: ∆L = 0, ∆S = 1, ∆T = 1
