Approximate Energy Expression for Symmetric Nuclear Matter with Central Forces

概要

論文の詳細を見る
An approximate energy expression is proposed for infinite zero-temperature symmetric nuclear matter in which nucleons interact through two-body central forces depending on the two-body spin-isospin states. It is a functional of spin-isospin-dependent radial distribution functions, and includes the potential energies completely and the kinetic energies up to the main part of the three-body cluster terms. A notable feature of this expression is that it automatically guarantees the necessary conditions on the spin-isospin-dependent structure functions. This expression is conveniently used in the variational method; the Euler-Lagrange equations are derived and numerically solved for four typical potentials. The obtained energies per nucleon are shown together with the spin-isospin-dependent radial distribution functions and structure functions.
