Z dependence of K α xray satellite structure in heavyionatom collisions
Abstract
The spectra of K α x rays emitted as a result of heavyionatom collisions have been measured with a Bragg spectrometer using a variety of equal velocity (1.7 MeV/amu) heavy ions ranging from _{1}H to _{18}Ar incident on solid targets containing atoms of _{13}Al, _{17}Cl, and _{19}K. In the cases of Cl and K, the measured K α_{1,2}K α satellite energy differences for one through seven Lshell vacancies were found to be systematically larger than those calculated using the HermanSkillman HartreeFockSlater program. Values of the binomial probability parameter obtained by fitting the relative satellite intensities with binomial distributions have been compared to theoretical values calculated using an impactparameter formulation of the binaryencounter approximation. In the Al spectra obtained with S and Ar ions, the K α_{1,2} peak is observed to have an intensity six to seven times larger than is expected on the basis of a binomial fit to the satellite peaks.
