Spectroscopy in the Second Minimum: Isotopic Limits, Lifetimes, and Magnetic Properties of Superdeformed Tl Nuclei
1University of Tennessee, Knoxville, TN 37996-1200, USA.
Abstract:
In-beam γ-ray spectroscopic studies of superdeformed bands in the mass 190 region are discussed with emphasis on recent results for Tl nuclei. Among those results, superdeformation at the edge of the region (in (189)Tl) and the first measurement of a superdeformed quadrupole moment in an odd-Z nucleus ((191)Tl) is presented. The experiments were conducted with the Gammasphere array at the Lawrence Berkeley National Laboratory. They are examples for the type of physics addressed in the first phase of Gammasphere operation.

As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are...

Atomic Nuclei: Types of Nuclear Relaxation
In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers...
