Even-odd effects in prompt emission in fission

Different average prompt emission quantities (as a function of A, of Z, of TKE and total average ones)-being dependent on fragment distributions-are affected by the even-odd effects in Y(A,Z,TKE). The N even-odd effect in neutron separation energy and the Z even-odd effect in the charge deviation enter the primary multi-parametric matrices of prompt emission quantities (e.g. ν(A,Z,TKE)) which are not depending on fragment distributions.
