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