The /sup 40/Ca(p,n) reaction at E/sub p/ = 159.3 MeV excites a state at E/sub x/ = 2.7 +- 0.1 MeV in /sup 40/Sc. The energy dependence and differential cross section angular distribution for this reaction indicate that this state is the T/sub z/ = -1 analog of a known 1/sup +/ state at E/sub x/ = 10.32 MeV in /sup 40/Ca. We find that the Gamow-Teller strength for this 0/sup +/..-->..1/sup +/ (p,n) transition is B(GT) = 0.21 +- 0.04. Comparison of B(GT) to B(M1)up-arrow for the analogous M1 transition in /sup 40/Ca indicates a substantial orbital-current contribution to the M1 strength. The /sup 40/Ca(p,n) reaction also strongly excites a 2/sup -/ state at E/sub x/ = 0.77 MeV in /sup 40/Sc. Good agreement is found between properly normalized distorted-wave impulse approximation calculations and the measured differential cross sections for this transition at 159.3 MeV.
