Assault frequency and preformation probability of the emission process
A study of the assault frequency and preformation factor of the α-decay description is
performed from the experimental α-decay constant and the penetration probabilities
calculated from the generalized liquid-drop model (GLDM) potential barriers. To determine
the assault frequency a quantum-mechanical method using a harmonic oscillator is
introduced and leads to values of around 10 21 s− 1, similar to the ones calculated within
the classical method. The preformation probability is around 10− 1–10− 2. The results for …

A study of the assault frequency and preformation factor of the -decay description is performed from the experimental -decay constant and the penetration probabilities calculated from the generalized liquid-drop model (GLDM) potential barriers. To determine the assault frequency a quantum-mechanical method using a harmonic oscillator is introduced and leads to values of around s, similar to the ones calculated within the classical method. The preformation probability is around –. The results for even-even Po isotopes are discussed for illustration. While the assault frequency presents only a shallow minimum in the vicinity of the magic neutron number 126, the preformation factor and mainly the penetrability probability diminish strongly around .
