The reaction 26Mg(d, [tau])25Na and the structure of 25Na

The nuclear structure of the nucleus 25Na has been studied with the (d, [tau]) proton pick-up reaction on 26Mg at a bombarding energy of 29 MeV with an energy resolution of 25 to 30 keV FWHM. Excited states in 25Na have been measured up to excitation energies of 8 MeV. The experimental angular distributions show good agreement with the predictions from the standard distorted-wave Born-approximation theory (code DWUCK; non-local and finite range). However, the agreement is improved considerably if the procedure of Kunz, Rost and Johnson is applied which accounts approximately for strong couplings to inelastic channels in the initial and final (strongly deformed) nuclei. The influence of this treatment on the evaluation of spectroscopic factors has been investigated and was found to be particularly pronounced for l = 0 transitions. The measured spectroscopic factors are compared to those from other experimental work and from shell-model and Nilsson-model calculations.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33894/1/0000159.pd
