High-energy calculation ofK-shell ejection cross sections as a function of projectile charge

High Energy Hadronic Total Cross-Sections

High energy hadronic total cross-section data are found to agree with the predictions of a QCD-string picture.

Projectile dependence of single-excitation cross sections at intermediate velocities.

We study 1s→2s(2p) excitation of hydrogen as a function of the nuclear charge of the projectile, ZP , for a fixed impact velocity, v51.3 a.u., for which electron excitation, capture, and ionization are competitive processes. For this purpose, we have performed large ab initio close-coupling calculations using a molecular basis in the framework of the impact-parameter method. Excitation probabil...

The Calculation of Photoionization Cross Sections

X-ray incoherent scattering total cross sections and energy-absorption cross sections by means of simple calculation routines

Simple but accurate expressions for the total cross sections and energy-absorption cross sections for inelastic scattering of x rays from atomic, molecular, and condensed matter are developed. The starting point is the relativistic impulse approximation for Compton scattering of x rays. This gives the inelastic-scattering cross-section differential with respect to energy and solid-angle interva...

High-energy reaction cross sections of light nuclei.

Here Rt(p) and Rl(t) are the projectile and the target radius, respectively. These authors found that the radii of "Li, ' Be, and ' Be were much larger than expected from the standard formula R = l.2 2 ' fm, where A is the mass number. They also checked Eq. (l) with Cilauber calculations using phenomenological densities. Theoretical densities from Hartree-Fock theory were applied to Glauber mod...
