This topic deals with the study of correlation of ground and excited states of even nuclei like 16O and 4He. The main objective of present work is to develop more theoretical techniques applicable in nuclear physics. The work is also extended to discrete excited states as well as odd even nuclei. The work is useful for the calculation of nuclear many body problems for spherically symmetric nuclear quantization representation. The ground state calculation of 16O and 4He are done using G matrix, which also help in calculation of ground state binding energy and one body two body densities.This topic deals with the study of correlation of ground and excited states of even nuclei like 16O and 4He.

Algebraic Collective Model Description of $^{166}$ ErAlgebraic Collective Model Description of $^{166}$Er

G. Thiamová

A simple, four-parameter algebraic collective model (ACM) Hamiltonian is used to describe 166Er. In this nucleus anharmonic double-γ vibrations are observed and the third excited 0+ state has been identified as a candidate for a bandhead of a β band. In contrast to γ-vibrational bands, systematically observed in deformed nuclei, β-vibrational bands are rarely well realized in nuclei and their observation and interpretation is still far from satisfactory. The purpose of the present paper is to show how the ACM model is capable to address complex properties of deformed nuclei in this region and what are its successes and weak points.A simple, four-parameter algebraic collective model (ACM) Hamiltonian is used to describe 166Er.
