Abstract

We describe how polarization-transfer data can be used to identify J π = 0 −, 1 −and 2 − components of the ΔT = 1, ΔL = 1, ΔS = 1 isovector “spin-dipole” resonance seen in charge-exchange reactions at medium energies. Data for 40Ca(p,n) are compared with distorted-wave impulse approximation (DWIA) calculations with theory of finite Fermi systems (TFFS) wave functions.
