Following a previously developed microscopic model, we show that the time of flight (TOF) spectra and the angular resolved fluxes (ARD) of thermally desorbed Ne atoms from Cu(111) are not appreciably affected by intrabound state cascading mediated by one phonon processes, in the surface temperature range 4 less-than-or-equal-to T less-than-or-equal-to 36 K, although inclusion of such processes increases the desorption time of about a factor 2 at T = 36 K. Our system, being a model for thermal desorption of light noble gases, shows that intrabound state cascading effects are not relevant in explaining the TOF spectra and the ARD at low substrate temperatures.

Abstract

Following a previously developed microscopic model, we show that the time of flight (TOF) spectra and the angular resolved fluxes (ARD) of thermally desorbed Ne atoms from Cu(111) are not appreciably affected by intrabound state cascading mediated by one phonon processes, in the surface temperature range 4 less-than-or-equal-to T less-than-or-equal-to 36 K, although inclusion of such processes increases the desorption time of about a factor 2 at T = 36 K. Our system, being a model for thermal desorption of light noble gases, shows that intrabound state cascading effects are not relevant in explaining the TOF spectra and the ARD at low substrate temperatures.
