On the formation of exfoliation on the reverse unbombarded face of a tungsten foil under MeV alpha particle irradiation
Formation of a very large exfoliation has been observed under SEM on the reverse unbombarded surface of a tungsten foil of thickness comparable to the projected range of 30 MeV alpha particles incident on the sample. Blister parameters like skin thickness, diameter or size, height of the surface layer from the base, pressure etc. are estimated using scanning electron micrographs. The present results vindicate the gas pressure model of blister formation.
