Resonant electron transfer in slow collisions of protons with Rydberg hydrogen atoms

The resonant charge-transfer reaction of protons on highly excited hydrogen atoms is considered by taking into account both the tunneling (under-barrier) and the over-barrier (classically allowed) electron transitions. It is demonstrated that in a wide range of variation of the reduced velocity v =...

Description
Summary:The resonant charge-transfer reaction of protons on highly excited hydrogen atoms is considered by taking into account both the tunneling (under-barrier) and the over-barrier (classically allowed) electron transitions. It is demonstrated that in a wide range of variation of the reduced velocity v = vn, the classical transition mechanism is predominant. Cross-section calculations for principal quantum numbers n between 10 and 50 are presented. The results for n between 45 and 50 are compared with the available experimental data and with other theoretical calculations.
