Level lifetimes and quadrupole moments from projectile Coulomb excitation of A~130 nuclei.
Technische Universität Darmstadt
Dissertation, Bibliographie
Kurzbeschreibung (Abstract)
The chain of experimentally accessible Barium isotopes represents a broad field regarding the evolution of nuclear quadrupole collectivity from the shell closure at N=82 towards and even beyond spherical-to-deformed shape transitions. Several isotopes ranging from stable Ba-130,132 towards radioactive Ba-140,142 have been studied with the projectile Coulomb excitation technique including the application of the Doppler-shift attenuation method (DSAM). Thereby lifetimes of quadrupole-collective states of Ba-132 and Ba-140 could be determined for the first time. Furthermore the static electric quadrupole moments of the first 2+ states for Ba-130,132 and Ba-140,142 were determined. The results are compared to Monte Carlo Shell Model and Beyond-Mean-Field calculations.
