Designer Nuclei and Some of their Properties

Abstract

Recently ‘designer’ nuclei with large neutron excess, such as 11Li , have been produced to understand the role played by excess neutrons in studying the properties of new isotopes and to develop new nuclear theory, and to understand how such isotopes can be used to develop new fission and fusion processes for the development of nuclear energy. Using the idea of a nuclear core composed of neutron-proton pairs (np-pairs) surrounded by unpaired neutrons and the Bogoliubov technique, we have calculated the binding energy, binding fraction, specific heat, entropy, and transition temperature of such nuclei, and particularly the isotopes for which the ratio of neutron to proton number is approximately 1.554 or more since this is the ratio for fissile materials.
