Distortion Effects in theCa40(d, p)Ca41Reaction

A series of calculations has been carried out in which the optical-model parameters have been varied in the distorted-wave Born approximation. In this manner the theoretical ($d, p$) cross section has been obtained as a function of $V$, $W$, $R$, and $a$ for the ${\mathrm{Ca}}^{40}(d, p){\mathrm{Ca}}^{41}$ reaction. Some preliminary comments on the stripping due to the interior of the nucleus are also made. Using the results of these first calculations, an attempt is made to obtain best fits to the ($d, p$) angular distributions from four levels of ${\mathrm{Ca}}^{41}$ at 4.13- and 4.69-Mev incident energy.
