Title: Band termination of collective nuclear rotation

Speaker: Prof. Ingemar Ragnarsson, Lund Institute of Technology, Sweden

Abstract: In the high-spin rotational nucleus, the effect of the Coriolis term produces a tendency to align the angular momenta of individual single particles in a deformed rotating mean field in the direction of the rotation axis. This rotational alignment of the orbits of individual particles tends to create a density distribution symmetric about the rotation axis. The band termination of collective rotation is thus expected, when the density distribution about the rotation axis becomes symmetric, with the total angular momentum being the sum of the contributions of aligned individual particles.
