One-nucleon stripping reactions to discrete levels induced by a 480 MeVC12beam on aPb208target

Abstract
One-proton and one-neutron stripping reactions induced by a 480 MeV C12 beam bombarding a Pb208 target have been studied using a high resolution energy loss magnetic spectrometer. The reactions are governed by two selection rules which are naturally contained in the one-step exact finite range distorted wave Born approximation formalism. Relative intensities of the populated states are well reproduced by this formalism as well as the absolute values of the cross sections. Comparisons with the results of one-nucleon stripping reactions induced by a O16 beam on a Pb208 target at 793 MeV incident energy are also presented; in this latter case the absolute cross section values are not reproduced.
