TL;DR: In this paper, the authors integrated numerically the differential equation for temperature-programmed first order thermal desorption: dθ/dt = − θνexp( - E/kT), where θ is the coverage.

TL;DR: In this paper, the evaporation of clusters in their flight from the condensation zone in the nozzle until their detection was studied, and it was shown that the cluster concentrations converge to a characteristic distribution in a short time.
Abstract: This work deals with the evaporation of clusters in their flight from the condensation zone in the nozzle until their detection. This time is of order ${10}^{\ensuremath{-}5}$ - ${10}^{\ensuremath{-}3}$ sec, depending on the experimental setup. It is shown that the cluster concentrations converge to a characteristic distribution in a short time (\ensuremath{\sim} ${10}^{\ensuremath{-}8}$ sec) independently of the initial conditions. It is also concluded that both Ar and Xe small clusters arrive solid at the detection zone.

TL;DR: In this paper, the authors present a general theory for steady-state nucleation of pure gases, explaining this observation as a combination of two effects: the heating of the clusters by condensation and an induced Maxwellian motion by rocketlike emission of fast monomers from clusters.
Abstract: Recent experiments show that the translational temperature of clusters in a beam expansion increases with cluster size. We present a general theory for steady-state nucleation of pure gases, explaining this observation as a combination of two effects: the heating of the clusters by condensation and an induced Maxwellian motion by rocketlike emission of fast monomers from clusters.

TL;DR: In this article, the differential cross sections for atom scattering by surfaces with one-Rayleigh-phonon exchange are calculated using a Debye model for the solid and an exponential potential for the atom surface interaction.
