Popis:	The energy distribution of protons sputtered from a metallic glass sample Zr50Ni25Cu25 with 90% hydrogen embedded in the lattice was investigated. The energy distribution was measured for various energies of the primary Ar+ ions. It turns out that the energy dependence of the emitted protons is well represented by a combination of a Maxwell-Boltzmann distribution function for the sputtered neutrals and the ionisation probability of the hydrogen atoms. We conclude that the hydrogen atoms embedded in the disturbed lattice of the alloy behave like an ideal gas with a high atom temperature. The temperature determined in the experiments is in a good agreement with the energy transferred from the primary ions to the hydrogen atoms at the surface calculated by computer simulations.
