STUDY OF J DEPENDENCE IN (D,HE3) REACTION

The J dependence of the angular distributions in the (d,He3) reactions was experimentally observed at small angles in the 2p proton pickup. This J dependence is qualitatively reproduced by distorted-wave calculations which indicate that the effect arises mainly from the deuteron spin-orbit potential. The calculated angular distributions are strongly dependent on the Q value of the reactions and the incident deuteron energy. The calculations also show that the J dependence is localized at the surface of the nucleus, and is very sensitive to the volume of the real part of the deuteron optical potential. This sensitivity may be understood by considering the role of the spin-orbit term in the optical potential. The sensitivity of the calculated angular distributions to the other parameters is investigated. © 1969 The American Physical Society.
