Effect of model space size on finite-temperature hartree-fock calculations

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The energy, entropy and specific heat of20Ne and24Mg have been calculated within the finite-temperature Hartree-Fock approximation for a variety of model spaces. It is found that the size of the model space has a negligible effect on the thermal properties of these nuclei for temperatures up to a few MeV,i.e. just above the predicted shape transition. In particular the shape transition itself is adequately described within the 1s-0d shell space, enabling comparison with exact canonical-ensemble results for the same space. The success of the calculations in a surprisingly small model space will prove to be of great relevance to calculations in heavier nuclei.
