(d, p) stripping reaction and (d, d) elastic scattering on Cr50, Cr52, Cr53, Cr54 and Fe54, Fe56 and Fe57

Abstract A method is described for determining the absolute differential cross sections for reactions using a multi-angle magnetic analyser. The energy spectra and angular distributions of protons from the (d, p) reactions on the targets of enriched Cr50, 52, 53, 54 and Fe54, 55, 57 are studied. Altogether 153 levels of final nuclei are studied, including 48 new ones. The l and Θ2 values are obtained for 93 levels, including 58 new ones. A well-pronounced dependence of the cross sections for the (d, p) reaction on the parameter of the target nucleus symmetry is established. The occupation numbers of the neutron 2p subshell are found from the treatment of the experimental data using the sum rule and the results are compared with other data concerning the the (d, t) reaction. The isobaric spin constant of the nuclear optical potential is estimated by the shift of single-particle neutron levels after the addition of two neutrons.

Coulomb stripping in 58,62,64Ni(d, p)59,63,65Ni

Abstract The 58,62,64 Ni(d, p) stripping reactions have been studied up to a high excitation energy at an incident deuteron energy of E d = 2.9MeV. The spectroscopic factors (2 J +1) S for some excited states differ from those measured at an incident deuteron energy above the Coulomb barrier. For high excited states these anomalies can be explained by the wrong assignment of l n in previous investigations. For low-lying levels of the residual nuclei, the proton energy exceeds the Coulomb barrier and the anomalies observed are apparently due to multistep stripping.
