Abstract
Excitation of hydrogen atoms, being initially in the excited 2p state by colliding with protons (p) and antiprotons (p) is investigated within the impact parameter method. The calculation involves the n = 1,2,3,4 states of the target in addition to considers previously, in an incident energy range from 3 keV to 1000 keV. The effect of the electric charge of the projectile on the collision is discussed.
Highlights
Over the years many theoretical approaches have been formulated and implemented in detail to study ion-atom collisions
We investigate the effect of the coupling to higher excited states in the interaction of protons and antiprotons with hydrogen atoms being initially in the excited 2p states
Figure 1 presents the result of calculation of the cross sections for excitation of the individual 2p 0,1 - 3s states as well as averaged 2p-3s excitation of hydrogen atoms by protons and antiprotons
Summary
Over the years many theoretical approaches have been formulated and implemented in detail to study ion-atom collisions. The cross sections of the n = 3 excitations of hydrogen atoms being initially in the 2p and 2s states was considered by taking into account the coupling with all of the n = 1, 2, and 3 states.
