The two most important developments in nuclear physics were the shell model and the collective model. The former gives the formal framework for a description of nuclei in terms of interacting neutrons and protons. The latter provides a very physical but phenomenological framework for interpreting the observed properties of nuclei. A third approach, based on variational and mean-field methods. The structure of the neutron deficient Hg nucleus was investigated using the GASP γ-ray spectrometer. Hg nucleus was populated through the Gd(32 S,4n) reaction at a beam energy of MeV. Six bands were observed, four of them for the first time. The quadrupole deformations of the two stronger excited bands were measured using the Doppler shift attenuation method. Cited by: 2. Collective band of states; positive parity od| -1 and lst-1 states. 1. Introduction In the low lying positive parity spectra of many of the odd-A (fp) shell nuclei col- lective bands of positive parity states axe seen (StyoT_~R et al and references therein). Those states are strongly excited in the neutron and proton pick up rc-. In this regards, the importance of the vector boson in transitional deformed nuclei has been investigated by Georgieva, who investigated interacting two-vector-boson model of collective motions in.
Underlying structure of collective bands of nuclei and self-organization mechanism. Takaharu Otsuka (University of Tokyo, Japan) The interplay between the single-particle states and the collective modes has been one of the central subjects of nuclear physics since the very beginning. The structure of the collective bands in 84 Sr is investigated within the framework of the deformed configuration-mixing shell model based on Hartree-Fock states. The configuration space consists of the single-particle orbits 1 p 3 2, 0 f 5 2, 1 p 1 2 and 0 g 9 effective interaction, given by Kuo and modified by Bhatt, has been used. Shapes in Nuclei 3 3 3 • At low spins Ra has an octupole vibrational spectrum; the I+3 negative parity states are one ht higher in energy than the even parity states with spin I. • At "high-spins" the spectrum for Ra shows a 6I=1 sequence with alternating parity; consistent with a stable octupole deformation, and. The collective bands of negative parity are studied via a microscopic approach where Coriolis forces and octupole correlations are treated on an equal footing. The apparent moment of inertia of these bands are nicely reproduced.

Magnetic Rotation. Magnetic rotation occurs in nearly spherical nuclei. It is characterized by sequences of gamma rays reminiscent of collective rotational bands but with a quite different character. Namely, each photon carries off only.
