Abstract:
Atomic nucleus is a unique system where the interplay between
collective and single-particle degrees of freedom plays an important
role, especially in those nuclei where proton and/or neutron numbers
are odd. Nowadays a wealth of new data on the odd-nucleon systems has
become available. However, theoretical description of these systems,
particularly heavy nuclei, is a major computational challenge. We have
developed a novel theoretical method for calculating spectroscopic
properties of medium-mass and heavy nuclei with odd nucleon number,
within the framework of nuclear mean-field method and the algebraic
model of interacting boson-fermion system. The method has overcome the
computational difficulty in studying odd-mass nuclei, allowing an
accurate, systematic and efficient description of their spectroscopic
properties with only a few free parameters. Interesting applications
of the method include the quantum phase transitions of intrinsic
nuclear shapes and the test of fundamental symmetries in
octupole-deformed (pear-shaped) nuclei. These topics are beyond the
limits of conventional theoretical approaches.
