Hafnium to thorium M-shell X-ray production cross sections by proton impact

Measurements of absolute K-shell ionization cross sections and L-shell x-ray production cross sections of Ge by electron impact

Results from measurements of absolute K-shell ionization cross sections and La x-ray production cross sections of Ge by impact of electrons with kinetic energies ranging from the ionization threshold up to 40 keV are presented. The cross sections were obtained by measuring Ka and La x-ray intensities emitted from ultrathin Ge films deposited onto self-supporting carbon backing films. Recorded x...

Comparison of proton and helium induced M subshell X-ray production cross sections with the ECUSAR theory

M subshell X-ray production cross sections have been measured for Ma12, Mb1, Mc, M2–N4 and M1–O23 transitions representing all five M subshells. These experimental cross sections have been compared with the ECUSAR theory of Lapicki and four parameter fits are given to the experiment to theory ratios covering the proton and helium ion energy range from 0.5 to 3 MeV on thin W, Au, Pb, Th and U ta...

K-shell, L-shell and M-shell Ionization Cross Sections of Uranium Atom by Electron Impacts

The theoretical model, developed by Khare model, has been modified to calculate the total cross sections for K-shell, L-shell and M-shell ionization of uranium (Z=92) atom due to electron impact at incident electron energy from ionization threshold to 1 GeV. The various calculated cross sections are in remarkable agreement with available experimental data and other theoretical cross sections. P...

Proton-induced cross sections relevant to production of 225Ac and 223Ra in natural thorium targets below 200 MeV.

Cross sections for (223,)(225)Ra, (225)Ac and (227)Th production by the proton bombardment of natural thorium targets were measured at proton energies below 200 MeV. Our measurements are in good agreement with previously published data and offer a complete excitation function for (223,)(225)Ra in the energy range above 90 MeV. Comparison of theoretical predictions with the experimental data sho...
