SYSTEMATICS OF NEUTRON AVERAGE RADIATIVE CAPTURE CROSS SECTIONS <σnγ> AT 25 keV

    Graphical Abstract
    • Abstract
  • The systematic behaviours of average radiative capture cross sections <σ_(nγ)> at25 keV on mass number A, effective excitation energy U and level densityparameter a are studied. The systematics formula is found as follows:<σ_(nγ)>=0. 3482A~(-1.033)U~(-0.2438)α~(0.8569)exp (1. 011(αU)~(1/2)).
