The potential interaction energy U(z) of a helium atom with a flat surface of a solid z = 0 can be approximated by a rectangular well of some depth U0 and width a = 5 A, and U(z = 0) = + (figure). Assuming that the wave function of an adsorbed atom in the ground state reaches a maximum at z = 0.99a, estimate the size of the localization region (z) for adsorbed atoms in the ground state.
