WebBackground: Gamow-Teller (GT) transition strengths are key inputs for estimating weak reaction rates of importance for a wide variety of astrophysical applications. (n,p)-type charge-exchange reactions, such as the (t,3He) reaction used in this work, are commonly used for extracting the GT strength distribution in the β+ WebFermi and Gamow-Teller transitions correspond to two different forms of leading order behavior of the weak interaction Hamiltonian in the non-relativistic limit: = isospin transition matrix which turn protons to neutrons and vice versa = Pauli spin matrices, which lead to . = identity operator in spin space, leaving.
