Reactions of Cold Trapped CH+ Ions with Slow H Atoms
Original language description
The destruction of CH+ ions in collisions with H atoms has been studied in a temperature-variable 22 pole ion trap (22PT) combined with a cold effusive H-atom beam. The stored ions are relaxed to temperatures of T 22PT GREATER-THAN OR EQUAL TO 12 K. Thehydrogen atoms, produced in a radio frequency discharge, are slowed down to various temperatures of T ACC GREATER-THAN OR EQUAL TO 7 K. They are formed into an effusive beam. The effective density of the hydrogen atoms in the trap as well as the H2 background are determined in situ using chemical probing with CO2 +. The experimental arrangement allows us not only to measure thermal rate coefficients (T 22PT = T ACC), but also to extract state-specific rate coefficients k(J,T t) at selected translationaltemperatures T t and for the CH+ rotational states J = 0, 1, and 2. The measured thermal rate coefficients have a maximum at 60 K, k = (1.2 +- 0.5)x10^(-9) cm^(3) s^(-1). Toward higher temperatures, they fall off in accordance with previ
