Abstract

Excited states of ${}^{9}B$ and ${}^{10}B$ were studied by means of the ( $p, d$ ) reaction, using 33.6-MeV incident protons. Deuteron groups were observed corresponding to strongly excited levels in ${}^{9}B$ at 0.0-, 2.35-, 7.1-, and 11.75-MeV excitation and in ${}^{10}B$ at 0.0-, 0.72-, 1.76-, 2.15-, 3.57-, 4.75-, 5.10-, and 6.04-MeV excitation. Small deuteron yields were observed corresponding to excited states in ${}^{9}B$ at 2.8- and 14.6-MeV excitation and ${}^{10}B$ at 6.57- and 7.5-MeV excitation. The angular distribution for the elastic scattering of 33.6-MeV protons from ${}^{10}B$ was measured and fitted with an optical-model calculation to provide parameters for a distorted-wave Born-approximation (DWBA) analysis of the ( $p, d$ ) data. Angular distributions were taken for all the levels strongly excited in the ( $p, d$ ) reaction, and the results compared to a DWBA calculation. Spectroscopic factors were extracted and compared with theoretical intermediate-coupling calculations in the $1 p$ shell and with other ( $p, d$ ) and ( $d, t$ ) results. Spin assignments were made for the levels of ${}^{9}B$ strongly excited in the ( $p, d$ ) reaction. Difficulties in matching the shapes of the experimental angular distributions to DWBA calculations for pickup and stripping reactions involving light nuclei are discussed.
