“…Because of their convenient availability, and the chemical and crystallographic similarities between metal hydrides and tritides, rare-earth hydrides have been studied for many years as reactor moderators and target materials in neutron generators. [1,2] Among rareearth metals, scandium (Sc), yttrium (Y), and erbium (Er) are the most attractive ones due to their highcapacity H storage and different electronic structures. With H concentration increasing, a metal-H system undergoes different phases, transforming from an αphase (hcp structure) to a hexagonal trihydride phase through a β-phase (CaF 2 structure).…”

“…He, implanted either using high kinetic energies or by radioactive decay of tritium, induces a complex defect structure in metals due to He clustering and bubble formation, which increases with increasing He concentration [1]. As reactor moderators and target materials in neutron generators, rare-earth metal hydrides have been studied for many years [2][3][4][5][6][7]. In neutron tubes, either deuterium-deuterium or deuteriumtritium reactions are utilized to produce neutrons.…”

We have developed an empirical erbium–helium (Er–He) potential by fitting to the results calculated from the ab initio method. Based on the electronic hybridization between Er and He atoms, an s-band model, along with a repulsive pair potential, has been derived to describe the Er–He interaction. The atomic configurations and the formation energies of single He defects, small He interstitial clusters (Hen) and He–vacancy (HenV) clusters obtained by ab initio calculations are used as the fitting database. The binding energies and relative stabilities of the HnVm clusters are studied by the present potential and compared with the ab initio calculations. The Er–He potential is also applied to study the migration of He in hcp Er at different temperatures, and He clustering is found to occur at 600 K in hcp Er crystal, which may be due to the anisotropic migration behavior of He interstitials.
