Proton-γangular correlations in the reactionCr52(d,pγ)Cr53

Abstract

The reaction $^{52}\mathrm{Cr}(d,p\ensuremath{\gamma})^{53}\mathrm{Cr}$ has been studied at a deuteron energy of 10 MeV up to an excitation energy in $^{53}\mathrm{Cr}$ of about 5 MeV. The protons have been detected by use of a multidetector arrangement consisting of 8-11 silicon surface-barrier detectors.Particle-$\ensuremath{\gamma}$ coincidence measurements have been performed with a Ge(Li) detectro in and out of the reaction plane. Absolute double differential cross sections have been measured for particle angles between 20 and 160\ifmmode^\circ\else\textdegree\fi{} for several transitions with $l$ transfers of 1, 2, 3, and 4. From differential and double differential cross sections the experimental particle-$\ensuremath{\gamma}$ angular correlation functions as a function of the particle angle have been extracted. The differential cross sections and the angular correlation functions have been analyzed with distorted-wave Born approximation. It turned out that deuteron potentials giving four half wave lengths of the wave function inside the potential well yield the best agreement with both the differential cross sections and the angular correlation functions. The influence of the spin orbit potential on the angular correlation was found to be less important.NUCLEAR REACTIONS $^{52}\mathrm{Cr}(d,p\ensuremath{\gamma})$, $E=10$ MeV; measured differential and double differential cross sections.
