NEUTRON MATTER EQUATION OF STATE AND THERMAL-ENERGY OF NUCLEAR-MATTER

The equation of state of neutron matter is calculated by using the low est-order constrained variational method and compared with the results obtained by other methods. The modified Reid potential which contains N-N and N-Delta interactions and fits the scattering data is used in the neutron matter Hamiltonian. The explicit dependence of correlation functions on spin, isospin, angular momentum, density and tenser oper ators for all of the NN and N Delta channels as well as temperature is taken into the account in our calculation. Free energy, effective mas s, etc of neutron matter plus thermal and compression energies of nucl ear matter are calculated. These results are compared with the recent calculations which have been obtained by using other methods.
