Abstract

After recoil implantation of Coulomb-excited ${}^{57}{Fe}$ into $α - Z r$ at 24 K, 30% of the implanted atoms end up on interstitial positions where they experience large electric field gradients. Between 40 and 100 K the quadrupole splitting shrinks by a factor of 2 accompanied by a sharp decrease of the line intensity. This effect is interpreted as a localized diffusion of the Fe atoms jumping in the octahedral cage of the hcp Zr lattice.
