The angular distributions, from 10 to 160 , of the emergent particles from the reactions Be/sup 9/(d,p) Be/sup 10,10*, B/sup 10/(d,p)B/sup 11,11*, and B/sup 11/ (d,n)C/sup 12,12*/ were investigated. The proton distriteron energies of 10, 9.2, and 8.1 Mev while the neutron distributions were obtained with 10-Mev deuterons. The proton distributions are analyzed using the Butler theory of deuteron stripping and, with the exception of the distributions from B/ sup 11*/, are in agreement with l/sub n/ =1 at forward angles. The distributions tom the first excited state of B/sup 11/ are not in agreement with any curves based upon the Butler theory, indicating that stripping does not play a major part in this reaction. The neutron distributions are analyzed using the treatment of Owen and Madansky, which allows heavy-particle stripping as well as Butler stripping. Reasonable agreement between the data and this theory for the ground state is obtained by using approximately equal amplitudes for Butler and exchange stripping and angular momenta of l = 1 and l = 0, respectively, for deuteron and exchange stripping. The analysis of the distribution for the first excited state of C/sup 12/ shows l = 1 for deuteron stripping, but does not provide a unique choice for the angular momentum in exchange stripping.
