Abstract：
It is assumed that ⁸Be consists of two α-particles which are close to each other in configration space. A spectroscopic density of ⁸Be-cluster in the residue nuclei is them obtained which is proportional to the square of the preformation probability of α-particle at nuclear surface. Using the improved method of parametrization of EFRDWBA overlap integral^[1], We calculate the double diffirential energy spectra and angular distributions of α-particles for the reactions ²⁰⁹Bi(¹²C, α) ²¹⁷Fr and extracte the preformation probability of α-particle at the surface of ²¹⁷Fr nuclei from fitting the experimental data. The agreement within the range of calculation error between the preformation probabilities extracted from transfer reactions and α-decay suggests that the reaction ²⁰⁹Bi(¹²C, α) ²¹⁷Fr may be explained as a diuble α direct transfer process.

Abstract:

It is assumed that ⁸Be consists of two α-particles which are close to each other in configration space. A spectroscopic density of ⁸Be-cluster in the residue nuclei is them obtained which is proportional to the square of the preformation probability of α-particle at nuclear surface. Using the improved method of parametrization of EFRDWBA overlap integral^[1], We calculate the double diffirential energy spectra and angular distributions of α-particles for the reactions ²⁰⁹Bi(¹²C, α) ²¹⁷Fr and extracte the preformation probability of α-particle at the surface of ²¹⁷Fr nuclei from fitting the experimental data. The agreement within the range of calculation error between the preformation probabilities extracted from transfer reactions and α-decay suggests that the reaction ²⁰⁹Bi(¹²C, α) ²¹⁷Fr may be explained as a diuble α direct transfer process.
