Abstract

The course of the partial cross section for the direct formation of $N^{13}$ in its ground state only in the reaction $C^{12} (d, n) N^{13}$ has been followed up to $E_{d} = 20$ Mev by observing the $N^{13}$ activity induced in a stack of polyethylene foils (only the ground state is stable against proton emission). The cross section falls appreciably less rapidly than would be expected for compound nucleus formation and also less rapidly than predicted by simple stripping theory. The cross section at $E_{d} = 8$ Mev is 100 mb which is not so large relative to that for the mirror ( $d, p$ ) reaction as is predicted by simple stripping theory. The reaction $C^{12} (d, t) C^{11}$ has been detected and its total cross section measured from its threshold ( $E_{d} = 14.5$ Mev) to $E_{d} = 20$ Mev where it is 10 mb. The magnitude of this cross section indicates that this is a pickup reaction.
