Abstract:
In this work, the thermal properties of double magic 40Ca nucleus have been investigated. Mean field calculations are performed. An effective Hamiltonian is based on Nijmegen (Nigm.II) potential. The framework of the constrained finite temperature Hartree-Fock (FTHF) method is used. The calculations are performed in no-core model space consisting of six major oscillator shells (i.e. 21 single particle orbits). The sensitivity of the thermal properties such as: binding energy, nuclear radius, entropy and free energy, is investigated to the degree of heating. This study was carried in a temperature range zero to 8 MeV. As the temperature of nucleus is increased by 8 MeV, it shows about 310.917 MeV of excitation energy to achieve a 29.8% volume increasing during heating. It means that volume coefficient of expansion of the nucleus is increased with increased temperature. The specific heat of the nucleus is decreased as the temperature is increased. The free energy of the nucleus is inversely proportional with temperature. The volume of the nucleus approximately undergoes quadratic radial expansion with temperature. Finally the entropy behavior exhibits almost a linear dependence on temperature for T > 1MeV, the absence of response at low temperature is due to shell-closure effects.
