Abstract

The classical trajectory Monte Carlo method has been used to calculate the final product principal quantum state n f-distributions in electron capture collisions involving a proton incident on a Rydberg hydrogen atom in an ni = 25 state. The generalized eccentricity, defined by orienting the classical eccentricity of the electron's orbit relative to the incident ion, was varied to show how the final state n f-levels depended on this quantity over the range of reduced collision speeds v* = vp/ve = 1.0-2.4. Plots of the final product n f-distributions at low reduced velocities show a resonance peak near n f = 25 at all generalized eccentricities. At speeds of v* = 1.8-2.2, two peaks arise in the final product n f-distributions from collisions with circular targets. In these cases, one peak is centred on the resonance point of n f = 25, while the second peak migrates through higher n f-levels as v* increases and is believed to possibly be a new collision mechanism. This high n f-level peak reaches a maximum around v* = 2.2 before disappearing completely from the final product n f-distributions by v* = 2.4, leaving only the resonant peak near n f = 25.
