An influence of superfluidity on chemical reaction has been studied in the recombination reactions of hydrogen (H) and tritium (T) atoms, H + T → HT and T + T → T2, in 3He-4He mixture solutions at 1.6 K. The reactive species, H and T atoms, were produced in the mixture through the nuclear reaction, 3He + n → p(H) + T. Experimental yield ratio of HT to T2 was 110 ± 17 in normal-fluid solution. However, in superfluid solution, the value decreased to 60 with a decrease in atomic fraction of 3He. A two-fluid model was applied to estimate the contribution of superfluidity. The calculated yield of HT to T2 in the superfluid component became almost a constant value of 56 ± 14 over the whole range of superfluid solution studied. On the basis of preferential formation of HT over T2 and a computer simulation of relative rate constants, formation of hydrogen isotope bubbles and their tunneling recombination were proposed.
