'Stripping' of the atom in bremsstrahlung

Polarizational bremsstrahlung in collisions of slow atomic particles

“…Indeed, the expressions (42) and (45), following from the adiabatic consideration of the process, correspond to the results of the Born theory of PBr [16,17]. The differential cross-section of the radiative capture contains the additional small factor t/E, being the electron capture probability in the collision.…”

“…Substituting the matrix elements (28 29) for the expressions for integrals I~, Iy and I~ (16)(17)(18) and performing simple transformations, one derives the result:…”

“…The differential cross-section of the radiative capture contains the additional small factor t/E, being the electron capture probability in the collision. Keeping these remarks in mind and starting from the formulae presented in [16,17], it is very easy to derive the result In this expression N1; 2 are the number of electrons in the first and in the second ion respectively; cq; 2 are the static polafizabilities of ions. Nevertheless, they can be simply generalised to the case of collisions involving many electron ions.…”

Polarizational bremsstrahlung in non-relativistic collisions

“…These arguments allow one to construct an approximate expression for the total BrS amplitude for photon energies lower than the 1s-shell ionization threshold [22]. For a fixed value of ω the target electrons can be divided into two groups, the 'inner' and the 'outer' electrons.…”

Theoretical study of transitions involving three rydberg series in two‐valence electron systems: MgI and its electronic sequence

“…Both procedures give extensive account of electron correlation. Also included in Table I1 are some Hartree-Fock (HF) f values [34], J7 set, which seem to be too high in magnitude, even compared with the By comparing the two sets of Q D O~ values, we find it convenient to explicitly include core-valence polarization in our calculations, and so we have done in the rest of the transitions and atomic species studied in the present work.…”
