"Impact Parameter Related Final N-level Splitting Observed in Aligned I" by K. R. Cornelius and Ronald E. Olson
 

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.
