A SYNTHESIS LEVEL DENSITY FORMULA

  • Based on the recommended level density formula of the Fermi gas model and considering the modifications at low excitation energy,a synthesis level density formula is proposed.From the mean neutron resonance spacing Dexp for 248 nuclei and the cumulative numbers of levels for 529 nuclei,a set of parameters is determined.

Abstract: Based on the recommended level density formula of the Fermi gas model and considering the modifications at low excitation energy,a synthesis level density formula is proposed.From the mean neutron resonance spacing Dexp for 248 nuclei and the cumulative numbers of levels for 529 nuclei,a set of parameters is determined.
