摘要：

The tensor-optimized Fermi sphere (TOFS) theory is applied first for the study of the property of nuclear matter using the Argonne V4' NN potential. In the TOFS theory, the correlated nuclear matter wave function is taken to be a power-series type of the correlation function F, where F can induce central, spin-isospin, tensor, etc. correlations. This expression has been ensured by a linked cluster expansion theorem established in the TOFS theory. We take into account the contributions from all the many-body terms arising from the product of the nuclear matter Hamiltonian H and F. The correlation function is optimally determined in the variation of the total energy of nuclear matter. It is found that the density dependence of the energy per particle in nuclear matter is reasonably reproduced up to the nuclear matter density rho similar or equal to 0.20 fm(-3) in the present numerical calculation, in comparison with other methods such as the Brueckner-Hartree-Fock approach.
