Abstract
PROF. J. E. LENNARD-JONES and A. F. Devonshire suggest an explanation of the anomalous reflection and diffraction of helium atoms by lithium fluoride, observed by Frisch and Stern. They show that atoms incident on a solid surface may, under certain conditions, be diffracted along and not away from the surface, a process they call ‘selective adsorption’. From the observations, they are able to deduce information about the energy levels of adsorbed helium atoms on a lithium fluoride crystal.
