Calculated proton-induced L-shell ionisation and X-ray production cross sections for Tc, Pm, Os, Po, At, Rn, Ra and Ac

The L-shell ionisation and X-ray production cross sections of the elements: Tc, Pm, Os, Po, At, Rn, Ra and Ac, whose experimental cross sections are scanty due to their radioactive, toxic and unstable nature have been calculated. Computer codes were employed in the targets cross sections calculation for incident protons of 1.00–10.00 MeV energy range. The obtained cross sections were validated in a similar procedure for Osmium ( Z 2 = 76 ) induced by protons of energies 0.10–1.00 MeV and were compared with experimental data. The calculated cross sections for the Osmium target were in good agreement with the experimental data. Hence, the calculated cross sections for the considered industrially relevant targets will be a valuable addition to existing database of elements induced by protons.
