AbstractAbstract
[en] The angular distributions relative to the ground-state and the first two excited states of 145Eu populated by the reaction 144Sm(16O,15N), at E(lab)=68MeV, are correctly described by DWBA calculations using the spectroscopic factors of the (He,d) reaction and a normalization equal to 1. The shape of the ground-state angular distribution in 144Sm(16O,14C)146Gd is well reproduced, while the experimental angular distribution relative to the first 2+ state seems to be shifted to forward angles. Angular distributions of the Q(opt) with 144Sm are very different from those obtained with 152Sm target. DWBA for 144Sm accounts for the shape but does not reproduce the absolute values

Les distributions angulaires relatives a l'etat fondamental et aux deux premiers etats excites de 145Eu peuples par la reaction 144Sm(16O,15N) a E(lab)=68MeV sont correctement decrites par un calcul DWBA en employant les facteurs spectroscopiques de la reaction (3He,d) et une normalisation egale a 1. La forme de la distribution angulaire a l'etat fondamental dans la reaction 144Sm(16O,14C)146Gd est bien reproduite tandis que la distribution angulaire experimentale relative au premier etat 2+ semble etre deplacee vers l'avant. Les distributions angulaires du Q(opt) pour une cible de 144Sm sont tres differentes de celles obtenues pour une cible de 152Sm. Le calcul DWBA, pour le 144Sm rend compte de la forme mais ne reproduit pas les valeurs absoluesOriginal Title
