摘要：

gamma-phase RCo(3)D(-4) deuterides with R=Y and Er were studied by neutron diffraction analysis at room temperature in the paramagnetic state. Deuterium atoms are distributed over three types of interstitial site 18h(2), 36i(1) and 36i(2) with occupancies of about 90%, 35% and 10% respectively. The deuterium site occupation is compared with that for beta-phase RCo(3) hydrides and with RCo(2) and RCo(5) structures from which the RCo(3) lattice can be constructed.
