Abstract:
A systematic investigation on the different processes involving formation, destruction and (de)excitation of specific rovibrational states of CH+ has been carried out based on statistical approaches. Thus, reactive collisions between C+(2P) and H2(v, j) and between CH+(v, j) and H for a large number of state-to-state transitions have been studied using a statistical quantum method and a statistical adiabatic channel model. The capabilities of such techniques for the study of the title system are discussed with comparisons to previous quantum mechanical results and experimental data. Integral cross sections as a function of the energy and rate constants in terms of the temperature (up to 1500 K) are obtained and numerical data for astrophysical purposes are provided.

Probability in Statistics
An example of a simple event is a coin toss. The result of a coin toss is either a head or a tail. Here, head and tail are two simple events. These two simple events make up the sample space. Further, the probability of an event occurring falls within the range of 0 to 1. The probability of an...
