Reexamination of a novel determination of density, temperature, and symmetry energy based on a modified Fisher model

摘要: In this article, a mistake in the formulation of modified Fisher model (MFM) derived pioneering works Purdue group is addressed and corrected by reversing sign mixing entropy term original formulation. The errors results previous MFM-related studies, such as isotopic yield distribution, isobaric ratios, isoscaling, $m$ scaling, self-consistent determination density, symmetry energy, temperature, density temperature related to intermediate mass fragment (IMF) freezeout, are quantitatively analyzed. It found that originating from generally small even have no effect some cases.
