A Lattice Location Study of Oxygen in Vanadium by 1-MeV Deuteron Channeling

Abstract

A direct determination of the lattice location of oxygen in vanadium single crystals has been made by means of ion channeling and the ion-induced nuclear reaction, 16 O(d, p) 17 O * . Channeling angular distribution measurements along principal axial and planar directions indicate that oxygen atoms occupy the octahedral interstices in vanadium. The shapes of the flux peaks observed for the [100], [110] and [111] directions have been compared with those of the theoretical curves calculated on the multiple strings model assuming statistical equilibrium.
