True ternary fission and the rotation effect

  • F. F. Karpeshin
Proceedings of the LXVI International Conference on Nuclear Spectroscopy and the Structure of Atomic Nuclei


Path calculations for fragments of the spontaneous true ternary fission of a 252Cf nucleus are performed. The results are considered from the standpoint of symmetries underlying the generalized nuclear model, and substantiation of the physical picture of the coaxial emission of the fragments during true ternary fission. The calculations are performed with allowance for the ROT effect, which is regarded as a major disturbance in this scenario. The obtained results are in agreement with experimental data.
