Dependence of the Angular Distribution of the (d, p) Reaction on the Total Angular-Momentum Transfer

Abstract

Experimental evidence is presented that the angular distribution of the ($d, p$) reaction depends not only on the orbital angular momentum $l$ but also on the total angular-momentum transfer $J=l\pm \frac{1}{2}$. For $l=1\mathrm{}$, marked differences appear between $J=\frac{1}{2} \mathrm{and} \frac{3}{2}$ at angles greater than 90° in medium-weight nuclei. Lesser differences also appear for $l=2\mathrm{}$ and $l=3\mathrm{}$ transitions at back angles. A marked dependence on $J$ is also observed for $l=2\mathrm{}$ transitions at forward angles. The experimental evidence for such effects is presented.
