Abstract

Hydrogen and deuterium ions were implanted in pure and boronised graphites at temperatures of 300-1850 K. Below 1000 K, the implanted deuterium (or hydrogen) was found to be reemitted in the form of molecules, i.e. D(2) or H(2). Above 1000 K, the reemitted particles consisted of both molecules and atoms, with the atom fraction monotonically increasing with increasing temperature, reaching a value of 95 % at 1850 K.
