Abstract

Targets containing Mg 26, Si 28, Si 29, Ca 40 and Cd 110 have been bombarded with tritons of about 10 MeV. In many cases excellent agreement has been obtained between the measured proton angular distributions from the (t, p) reactions and the predictions of plane wave double stripping theory. The Mg 26(t, p)Mg 28 reaction has provided unambiguous determinations of the spins and parities of a number of states in Mg 28 which were previously unknown. Spin-parity assignments from the reactions Si 28(t, p)Si 30, Si 29(t, p)Si 31 and Ca 40(t, p)Ca 42 are in good agreement with earlier measurements. In the case of the Cd 110(t, p)Cd 112 reaction an intense ground state transition was observed with relatively weak transitions to excited states. This may indicate the presence of an enhancement effect of the type suggested by Yoshida.
