Study of L-shell x-ray production cross section of Ta and Au by 20–55 MeV O5+ and F5+ bombardment
2011
Experimental work was performed at the HI-13 tandem accelerator in the Chinese Institute of Atomic Energy (CIAE). In this experiment, L-shell x-ray production cross sections were measured for solid Ta and Au targets by 20?55?MeV O5+ and F5+ ions. The L1, L?, L? and L?-subshell characteristic x-rays of Ta and Au were measured. The ratios ?(L?)/?(L?), ?(L?)/?(L?) and ?(Ll)/?(L?) of Ta and Au L-subshell production cross sections were calculated according to experimental data. The results are compared with the predictions of energy-loss Coulomb-repulsion perturbed-stationary-state relativistic theory. Fairly good agreement is obtained between the experimental and the calculated values.
