XLV. Angular distribution in (d, p) and (d. n) reactions

The angular distribution of the particles emitted in (d, p) or (d, n) reactions is calculated, assuming a stripping process, by means of the Born approximation. The result resembles in most respects that of more complicated calculations by S. T. Butler, but there are certain differences which are discussed in relation to experiments which have been, or may be done. The particles are emitted mainly at fairly small angles to the incident direction, and the precise shape of the distribution is simply related to changes of angular momentum and parity occurring. The principal unknowns in the formulae are matrix elements, which may be estimated for sufficiently high energies by the statistical method.
