Critical temperature of nuclear matter at the liquid-gas phase transition in a nonlinear field theoretical model

Abstract

In Walecka's mean field theoretical model complemented with nonlinear terms, we search for the value of the critical temperature of nuclear matter compatible with the experimental data, i.e. with the observed binding energy, density, and compressibility of nuclear matter at zero temperature. Our result is in the region of the other theoretical estimates [5]…[9], but is much higher than the result obtained from experimental data [4].
