Charge-transfer processes in collisions of slowH+ions with hydrocarbon molecules:CH4<

Observation of the Isomer Effect on Charge Transfer fromC3H4Molecules (Allene and Propyne) at keV Energies

“…The theoretical result including the vibrationally excited state up to y f 5 for the product molecular ion shows much better agreement with the measurement in the energy dependence. This trend has been pointed out for the first time by the present authors earlier [12,13]. Charge transfer to the ground ͓C͑ 3 P͒ 1 C 3 H 1 4 ͔ channel constitutes approximately 15% for allene and 25% for propyne of the total charge transfer at 1 keV.…”

Collisional induced double electron loss of NO− and CH4− anions below 10 keV energies

“…Since no absolute measurements were possible with the present experimental setup, we have calibrated our experiment to those of well known electron capture cross section of protons on Ne and CH 4 that were measured in the same energy range by Kusakabe et al [18], Allison [19], Rudd [20] and Lindsay et al [21]. The calibration was suitable for all cases.…”

Electron capture in intermediate-to-fast heavy ion collisions with neutral atoms

“…Although there are a few experimental studies (see, e.g., [15,16,[35][36][37]), any detailed theoretical treatment of the electron-capture process at low energies taking into account molecular effects, even for the simplest system like H 2 , has not been established so far. It is noteworthy that the cross sections for molecular targets also may depend on their vibrational states during the collision, particularly at very low energies [30].…”
