Investigation of octupole deformations in the Fr217 nucleus by yrast spectroscopy

Creators

Description

The spectroscopic characteristics of the yrast levels of Fr217 are determined. The level scheme up to a value of J = (39/2+) for angular momentum and parity is established. The production of the Fr217 nucleus in a heavy ion collision reaction was only possible by using a radioactive Pb210 target. The method for preparing the target is described. The Fr217 nucleus belongs to the category of nuclei showing octupole effects. Mass A = 217 seems to be the lower limit of the region where these effects occur

Abstract (French)

Les caracteristiques spectroscopiques des niveaux yrast du Fr217 sont determinees. Le schema de niveaux jusqu'a la valeur J = (39/2+) de moment angulaire et de parite est etabli. La production du noyau Fr217 dans une reaction de collision d'ions lourds n'a ete possible que grace a l'usage d'une cible radioactive de Pb210. La methode de preparation de cette cible est decrite. Le noyau appartient a la categorie de nuclides presentant des effets octupolaires. La masse A = 217 apparait comme la limite inferieure de la region de nucleides ou ces effets ont lieu
