The Mass and Isotope Distribution of Limiting Temperatures  Summary Limiting temperatures decrease with the system size, which is independent of the force used. Limiting temperature is sensitive to the effect N-N interaction and the surface tension. Moreover,symmetry-surface tension term makes limiting temperature curve more close to experimental data. 10/28/2019 The Mass and Isotope Distribution of Limiting Temperatures

The Mass and Isotope Distribution of Limiting Temperatures The isotope distribution of limiting temperatures appears to be a parabolic shape. The centroid of the parabolic curve is not located at the isotope on -stability line(T=0) but incline to the neutron-rich side. The symmetry-surface tension term raises limiting temperatures of neutron-rich isotopes. 10/28/2019 The Mass and Isotope Distribution of Limiting Temperatures

The Mass and Isotope Distribution of Limiting Temperatures The thermal stability line for hot nuclei is more Neutron-rich compared to -stability line. And when the symmetry-surface tension term is taken into account, the thermal stability line shows a trend to Neutron-rich further more, especially for heavier nuclei.
