Evidence for the HCl+(A) formation in the reaction of Ne(P-3) with the size-selected HCl dimer using an electrostatic hexapole field
Penning ionization of Ne(P-3) metastable atom with size-selected HCl dimer was studied by using an electrostatic hexapole field and chemiluminescence detection. We found that the HCl dimer can also produce HCl+(A) ions in the reaction with Ne(P-3) just like its corresponding monomer reaction. The internal energy distribution of HCl+(A) in the dimer reaction is cooler than that in the monomer reaction, reflecting the third-body effect due to the other HCl in the dimer.
