Angular Distribution of Protons from theCa40(d, p)Ca41Reaction

Abstract

Proton groups emitted from a thin CaO target under 7-Mev deuteron bombardment were studied with a magnetic spectrograph. Their angular distributions were analyzed in terms of stripping theory to determine the orbital angular momenta and relative reduced widths for neutrons captured to form levels in ${\mathrm{Ca}}^{41}$ up to 4.2-Mev excitation. Capture gamma rays measured elsewhere can be fitted to a scheme comprised of levels strongly excited in the ($d, p$) reaction. Evidence is found for single-particle $f_{\frac{7}{2}}$, $p_{\frac{3}{2}}$, and $p_{\frac{1}{2}}$ states, but the expected $f_{\frac{5}{2}}$ level does not appear. Relative cross sections and reduced widths for ($d, p$) reactions forming states in ${\mathrm{Ca}}^{43}$ and ${\mathrm{Ca}}^{45}$ are also tabulated.
