Abstract：
The method of parametrization of EFR-DWBA overlap integral developed by T.Udagawa and T.Tamura et al.,^[1] is improved. Using the improved method we have fitted the experimental double differential energy spectrum of ⁸Be-cluster coming from the reaction ²⁰⁸Pb (¹²C, ⁸Be) ²¹²Po leading to the continuum states and extracted the preformation probability of α-cluster at the surface of ²¹²Po nucleus. Within the range of calculation error, the result is in agreement with that extracted from fitting the experimental data of α-decay.
