Depth profiling and data analysis in slow position experiments reveal more information on the position implantation. The simulation of the behavior incident at different kilo electron volt energies are effected by the Monte Carlo simulations. The mechanisms of conduction- electron and longitudinal acoustic phonon scattering describe the final stages of position thermalization in Al, Cu and Au from 25 electron volts. The data, including implantation profiles, fraction and energy distribution of reemitted positron, are yielded by the Monte Carlo simulation.

The local electronic and chemical environment of TiC-modified Nd2Fe14B ribbons are studied using positron annihilation spectroscopy. Results show that higher concentration of alloying additions increases the shape parameter, S, of the symmetric Doppler-broadened positron-electron annihilation peak. This increase in S can be considered an increase in the amount of open volume in the quenched glass.
