Description

Alpha formation factor Fsub(1,m) introduced by Iwamoto and Harada, which represents the probability to form the alpha with 1 particles above the Fermi level and m particles below, is calculated based on the shell model. The result shows a close similarity to the Iwamoto and Harada's calculation which is obtained by use of the Fermi-gas model. This offers a foundation to their approximation and the insensitivity of Fsub(1,m) against the underlying model provides an approval to use Fsub(1,m) in the pre-equilibrium calculation. (author)
