文摘

Preformation of alpha-particles for all even-even alpha-emitters are determined. Penetrability is determined using four different versions of proximity potentials. Assault frequency is determined using a modified formula. Potential Prox 76 yields minimum and correct preformation values. Justification for use of Prox 76 is done through comparison of barrier parameters.
