Statical and Statistical Properties of Heated Rotating Nuclei in the Temperature-Dependent Finite-Range Model

Macroscopic temperature-dependent finite-range model is applied to calculate statical and statistical properties of heated rotating compound nuclei. The level density parameter was approximated by a leptodermous type expression. The coefficients of this expansion are in surprisingly good agreement with those obtained earlier by Ignatyuk and co-workers. The importance of taking into account simultaneously temperature and angular momentum of the nucleus on such properties as heights and positions of barriers, effective moments of inertia is considered. Temperature dependence of (Z²/A)_crit parameter and Businaro-Gallone point are also investigated. It was revealed that, both parameters moved to the range of lighter nuclei as temperature increased. It was shown that, temperature effects are qualitatively similar to angular momentum ones, but they are significantly smaller in most investigated cases.
