摘要: Abstract The global stability of the uniform ground state nuclear matter is tested relative to a π 0 -condensed characterized by static spin-(isospin-) waves. Strong correlations are introduced into trial wave functions for each phase, thereby permitting models realistic two-nucleon force be employed. In low cluster-order comparison, phases symmetrical and neutron emphatically favored over entire density range considered.
