We study the angular distribution of light diffusely reflected from a turbid medium with large (compared to the light wavelength) inhomogeneities. Using Monte Carlo radiative transfer simulations, we calculate the azimuthally averaged bidirectional r

It is commonly accepted that the Schwarzschild-Schuster two-flux approximation (1905, 1914) can be employed only for the calculation of the energy characteristics of the radiation field (energy density and energy flux density) and cannot be used to c

A theory of interatomic collision cascades in an infinite medium subject to inelastic energy loss (ionization slowdown) of particles is developed. Emphasis is on the angular and energy distributions of primary ions and cascade atoms upon slowdown. An

A new approach to the problem of sputtering is proposed. The approach is based on the invariance principle in combination with the method of separation of fluxes. The problem is considered for the case of linear cascades in amorphous materials. An in

The depth distribution of light ions under grazing incidence on the surface of a semi-infinite layer was analytically derived. It was assumed that the interaction between the ions and atoms of the medium is described by potentials in the form of an i

Two mechanisms of the recoil sputtering are investigated. The first one is connected with recoils generated by the inward flux of incoming ions while the second one – with those generated by the backward flux of ions reflected from the bulk of the

The value of the most probable exit angle of particles θmp transmitted through thin targets at inclined incidence of the beam is investigated both analytically and experimentally. A simple formula for θmp is derived as a function of ion energy, bea

Energy loss distributions of particles transmitted through free mylar foil of 25 μg/cm 2 thickness for 10–25 keV protons incident at angles 0 ≤ θ 0 ≤ 60° are measured. An analytical treatment is made using the Fokker-Planck approximation for

The characteristics of the energy spectra of kiloelectron-volt protons transmitted through a free-standing foil are investigated theoretically and experimentally as functions of the angle of incidence of the beam on the target. Analytical expressions

The problem is considered of small-angle reflection and transmision of charged particles in the case of grazing incidence of a broad beam upon the surface of a flat scatterer of finite thickness. Simple analytical expressions are obtained for the ave
