Born and four-state calculations for the excitation of the (2p)43s and (2p)53p levels of neon by proton impact

Abstract

For the singlet levels of (2p)53s and (2p)53p of the Ne atom wavefunctions of Hartree-Fock type are constructed. The Born calculations yield the new Bethe parameter bn=0.050 for the (2p)53p states. A four-state impact parameter calculation is carried out including the states 1S(2p)6, 1S(2p)53p and 1P(2p)53s (M=0,1). With this relatively simple model all known experimental data for the excitation of (2p)53s and (2p)53p by proton impact can be explained satisfactorily.
