Abstract：
The thermal stability for hot nucleus is investigated based on limiting temperatures. We calculate the isotope distributions of limiting temperatures for finite nuclear systems by using Skyrme interaction. The isotope distribution of limiting temperatures appears to be an upside-down parabolic shape, which looks very similar with the isotope distribution of the products of multifragmentation in intermediate energy heavy ion collisions. We systematically calculated the isotope distributions of limiting temperatures for a series of nuclei from light to heavy nuclei, and obtain a thermal stability line for hot nuclei. The thermal stability line is more neutron-rich compared with the β-stability line.
