“…The variance of the nuclear straggling distribution can be calculated for realistic potentials [17], but this result has little practical relevance: As was already pointed out by Schmelmer et al [18] and was shown recently by Glazov and Sigmund [19], the nuclear straggling distributions are asymmetric and strongly non-Gaussian with long low-energy tails. These tails lead to large variances of the distributions, but change the FWHM only slightly [18].…”

Angular and energy distributions due to multiple small angle scattering were calculated with different models, namely from the analytical Szilágyi theory, the Monte Carlo code MCERD in binary collision approximation, and the molecular dynamics code MDRANGE, for 2 MeV 4 He in Au at backscattering geometry and for 20 MeV 127 I recoil analysis of carbon. The widths and detailed shapes of the distributions are compared, and reasons for deviations between the different models are discussed.

“…The energy integrals in (5) and (6) anticipate that at room temperature the electron cannot gain energy from a dielectric wall and the functions η(ξ) and ξ(η) are implicitly defined by (2). To obtain the quantity Q(Eη|E η ) we employ the invariant embedding principle 17,20,24,34 , the essence of it is shown in Fig. 2.…”

“…The sticking probability for an electron approaching the wall of a plasma can thus be expressed by the transmission probability for the longranged surface potential times the probability to remain inside the wall despite of internal backscattering. Essential for our approach is the invariant embedding principle 17,20,24,34 . It allows us to extract from the overwhelming number of electron trajectories the few backwardly directed ones most relevant for sticking.…”

We describe a method for calculating the probability with which the wall of a plasma absorbs an electron at low energy. The method, based on an invariant embedding principle, expresses the electron absorption probability as the probability for transmission through the wall's long-range surface potential times the probability to stay inside the wall despite of internal backscattering. To illustrate the approach we apply it to a SiO2 surface. Besides emission of optical phonons inside the wall we take elastic scattering at imperfections of the plasma-wall interface into account and obtain absorption probabilities significantly less than unity in accordance with available electron-beam scattering data but in disagreement with the widely used perfect absorber model.

“…In a previous study [44] it was pointed out that corrections for nuclear stopping were performed in different ways by different authors and, with very few exceptions, insufficiently documented. There are at least two major uncertainties:…”

a b s t r a c tIn the slowing-down of heavy ions in materials, the standard description by Lindhard and Scharff assumes the electronic stopping cross section to be proportional to the projectile speed v up to close to a stopping maximum, which is related to the Thomas-Fermi speed v TF . It is well known that strict proportionality with v is rarely observed, but little is known about the systematics of observed deviations.In this study we try to identify factors that determine positive or negative curvature of stopping cross sections on the basis of experimental data and of binary stopping theory. We estimate the influence of shell structure of the target and of the equilibrium charge of the ion and comment the role of dynamic screening.
