摘要

The survival probability of a compound nucleus measures the competition among the neutron evaporation, light charged particle emissions and fission in the process of its de-excitation. It is considered as one of the crucial factors for producing superheavy elements, which is usually described by the existing statistical models[1]. In spite of the well developed statistical theory itself, however, due to the unclearness of the structure of superheavy nuclei, some characteristic quantities for evaluating the fission and particle emission widths are correspondingly ambiguous. This report gives the study on the odd-even effects of the survival probability based on a statistical model. The calculation details can be found.
