L-Shell Ionization of Gold by Heavy-Ion Impact investigations is less for heavier projectiles (Z. ≥ 3), and first of all the x-ray production cross-sections or the ratios of the cross-sections for the individual L-subshells were determined in these works in the high energy region. Thus, e.g. Li et al. (1976) showed that the ratios of the L-subs

An Analytical Expression for the Energy Differential PWBA K-Shell Ionization Cross Sectionss section in terms of the energy and momentum transfers. His calculation was carried out using hydrogenic wave functions to describe both the bound and the continuum electron states. The difficulties for additional useful simplifications of this expression are generally recognized. As a consequence

A Closed Formula for Low Velocity K-Shell Ionization Cross Section and the Universal Function in PWBrom the projectile to the target atom. The difficulties encountered for further simplifications of Bethe’s formula, which preserves its usefulness, point to the direction of numerical integrations over the momentum and the energy transfers. Numerical tables of nonrelativistic PWBA calculations for d

Cross Section for L-Shell Excitation in 6–40 keV Ar+-SiH4 Collisionsacancies to be transferred via molecular orbitals (MO) from empty levels of the projectile to inner shells of the collision partner. These inner-shell vacancies are then generally shared between the collision partners during the outgoing part of the collision.

K-Shell Excitation Mechanism in Close Impact Parameter Collisions between Ni Ions and Ni, Zr, Ag, Tesidered to be due to electron promotion. In near-symmetric and relatively light collision systems (Z., Z. ≲ 10) experimental impact-parameter dependent vacancy production probabilities, P(b), agree well with theoretical curves for 2pσ - 2pπ rotational coupling.. For heavier systems, a diminishing pe

X-Ray Production Cross Section for a Thin Solid Be-Target with Light Ions being the atomic number of projectile and target, respectively) and by molecular orbital (MO) interaction (Z. ≈ Z.). For details see e.g... The latter process usually is discussed as a three step mechanism: Vacancy production in the 2pir MO leading to a vacancy occupation number N. in the entrance

Outer Shell Projectile Ionization in Very Fast Heavy Ion Collisionsport measurements of secondary electrons with energies up to 7 keV produced in collisions of 60 MeV to 200 MeV Ne-ion projectiles with a neon gas target. A typical feature of the electron spectra is a pronounced peak, usually called an electron loss peak (ELP). The ELP is caused by the emission of p
