| Summary: | The atom-atom-ion three-body recombination (TBR) of mixed
He and X
(X = H or D) systems is investigated by solving the Schrödinger equation using the adiabatic hyperspherical representation method. It is shown that the dominant products after a TBR in the ultracold limit (E ≤ 0.1 mK × k
) are different for the two systems. For the
He
HeH
system, the rate of TBR into the
HeH
ion is nearly two orders of magnitude larger than that of TBR into the neutral
He
molecule. In contrast, the yield of
He
is a little higher than that of
HeD
for the
He
HeD
system. Furthermore, since the adiabatic potentials become more attractive and the nonadiabatic couplings become much stronger by substituting D for H in the
He
HeH
system, the total TBR rate for the
He
HeD
system is nearly two orders of magnitude larger than that for the
He
HeH
system. |
