A comparative study of the quasielastic barrier distributions of the 20Ne+92,94,95Mo systems was performed at the Heavy Ion Laboratory (HIL) of the University of Warsaw. The experiment aimed to study the influence of dissipation due to single-particle excitations on the barrier distribution structure. The preliminary results indicate that the larger number of single-particle excitations for the heaviest Mo isotopes leads to the smoothing of the barrier distribution, which loses the structure foreseen by the coupling to only collective excitations. Theoretical calculations performed including the coupling to the non-collective excitation are in good agreement with the experimental barrier distributions for the 20Ne + 92,94,95Mo systems.

Abstract
A comparative study of the quasielastic barrier distributions of the 20Ne+92,94,95Mo systems was performed at the Heavy Ion Laboratory (HIL) of the University of Warsaw. The experiment aimed to study the influence of dissipation due to single-particle excitations on the barrier distribution structure. The preliminary results indicate that the larger number of single-particle excitations for the heaviest Mo isotopes leads to the smoothing of the barrier distribution, which loses the structure foreseen by the coupling to only collective excitations. Theoretical calculations performed including the coupling to the non-collective excitation are in good agreement with the experimental barrier distributions for the 20Ne + 92,94,95Mo systems.Pubblicazioni consigliate
