摘要：

Pulsed laser desorption was used to investigate the reemission of deuterium implanted in beryllium. The amount of D-2 molecules released as a function of the laser energy density was measured on samples with different implantation energies and doses. Numerical modelling of our results indicates that detrapping and diffusion are the limiting processes. The data are best fitted with second order detrapping with a trap energy of 1.7 +/- 0.1 eV and the effective diffusion coefficient is described by the equation D = (8 +/- 1) x 10(-8) exp(-0.32 +/- 0.02 eV/kT) m(2) s(-1).
