Spontaneous fission half-life-times of double-odd nuclei (Z≧97)

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

Spontaneous fission half life times of odd-odd and even-even nuclei in the region 97≦Z≦109 and 140≦N≦ 160 are calculated. New Nilsson potential parameters (κ, μ) generating the proper single particle spectrum are estimated. Angular momentum projections of odd-odd particles are properly taken into account. Hindrance factors 5–7 orders of magnitude are found forZ≦101 nuclei and 1–3 orders of magnitude for nucleiZ≧ 103.
