On Microscopic Energy Corrections Around Scission Configuration

The spontaneous fission of actinides is analysed by the macroscopic - microscopic method based on the Lublin Strasbourg Drop model and the two deformed Nilsson wells or Yukawa folded single particle potentials. The microscopic corrections are obtained within the Strutinsky prescription and the BCS theory. In the scission point the shell correction possess the additive property but this is not true for pairing correlations during asymmetric fission. Here the shape dependent pairing force of the δ or Gogny type should be used and the pairing strength should grow with increasing deformation of fissioning nucleus. The examples of sponta- neous fission results are presented. The possibility of β decay accompanying the spontaneous fission is noticed.
