Electronic and photonic reactive collisions in edge fusion plasma and interstellar space: Application to H₂and BeH systems

Theoretical resonant electron-impact vibrational excitation, dissociative recombination and dissociative excitation cross sections of ro-vibrationally excited BeH+ ion

“…Thus, calculations seem to be the only way to obtain these data. For the BeH + ion the collision processes studied so far are the electron-impact electronic excitation [8] and the dissociative recombination [9][10][11][12][13][14]. In particular, we note that only a few studies considered vibrationally-excited BeH + ions [8,[12][13][14].…”

“…The cross sections of the above processes, for a number of initial rovibrational states + + v j , (and final + + w j , states in VE) are calculated in the energy range from threshold to 10 eV. The local complex potential results are compared with the results of multichannel quantum defect theory (MQDT) [10,[12][13][14][17][18][19][20][21].…”
