Proportionality between (t,3He) reaction differential cross sections and Gamow-Teller strengths.

The so-called unit cross section describing the proportionality between differential cross sections and Gamow-Teller transition strengths is studied for the case of the (t,$ ^{3}$He) charge-exchange reaction. Experimental data for H, and $ ^{12,13} $C targets taken at 115 AMeV are complimented by existing data for $ ^{2} $H, $ ^{6} $Li, and $ ^{26} $Mg. The (t,$ ^{3} $He) results are compared with results for the ($ ^{3} $He,t) reaction at 140 AMeV and for targets with 12
