Abstract
The thermodynamics property of finite heavy mass nuclei, with the number of protons greater than the number of neutron is investigated. The core of the nucleus contains the neutron-proton pair that interacts harmonically; the excess neutron(s) reside(s) on the surface of the nucleus and introduce the anharmonic effect. The total energy is evaluated using ladder operator method and the quantum mechanical statistical expression of energy. The total energy, heat capacity and entropy are found to depend on the occupation number of states and the number of excess neutrons. At temperature near absolute zero the specific heat and entropy are lowest because a decreases in temperature leads to a decrease in particle interaction and energy.
