Thick-target Ti and Fe K X-ray production cross sections from D, He, C, N and O bombardment

L-shell X-ray production of molybdenum and niobium induced by 1500–3500keV Xe26+ ions

“…In this model, the inner-shell electron will be ionized from the united-atom state [18][19][20]. Hence, for the present experiment, the theoretical production cross sections values will be calculated in the united-atom limit by using the bindingenergy-modified BEA model, within the quasi-molecular frame.…”

L-shell x-ray yields and production cross-sections of molybdenum induced by low-energy highly charged argon ions

“…The mechanism of the inner shell vacancy production is explained in the framework of MO. In 1985, Montenegro and Sigud had already discussed the direct ionization from 1sσ molecular states [13,14]. Lapicki and Lichten [12] also studied the direct ionization from 2pσ UA state for Ni+Ni collision.…”

“…In the MO model, the projectile-target system is represented as a temporarily formed diatomic molecule characterized by the adiabatic, independent-particle orbits and energies. Electrons will evolve to the MO and probably be ionized from these MO states [12][13][14]. We consider that the electrons of molybdenum L-shell will be ionized probably in the united atom (UA) limit and be ionized from the 3dδ, 2sσ and 2pπ MO of the UA.…”
