A dumbbell model with five parameters describing nuclear fusion or fission

  • We propose a five-parameter dumbbell model to describe the fusion and fission processes of massive nuclei, where the collective variables are: distance ρ between center-of-mass of two fusing nuclei, neck parameter ν, asymmetry D, two deformation variables β1 and β2. The present model has macroscopic qualitative expression of polarization and nuclear collision of head to head, sphere to sphere, waist to waist and so on. The conception of "projectile eating target" based on open mouth and swallow is proposed to describe nuclear fusion process, and then our understanding of the probability of fusion and quasi-fission is in agreement with some previous work. The calculated fission barriers of a lot of compound nuclei are compared with the experimental data.

A dumbbell model with five parameters describing nuclear fusion or fission

    Corresponding author: BAO Jing-Dong,

Abstract: We propose a five-parameter dumbbell model to describe the fusion and fission processes of massive nuclei, where the collective variables are: distance ρ between center-of-mass of two fusing nuclei, neck parameter ν, asymmetry D, two deformation variables β1 and β2. The present model has macroscopic qualitative expression of polarization and nuclear collision of head to head, sphere to sphere, waist to waist and so on. The conception of "projectile eating target" based on open mouth and swallow is proposed to describe nuclear fusion process, and then our understanding of the probability of fusion and quasi-fission is in agreement with some previous work. The calculated fission barriers of a lot of compound nuclei are compared with the experimental data.
