Influence of superfluidity on recombination reactions of H+T$$rightarrow$$HT and T+T$$rightarrow$$T$$_{2}$$ in $$^{3}$$He-$$^{4}$$He quantum media under saturated vapor pressure at 1.6 K

Aratono, Yasuyuki; Iguchi, Kazunari; Okuno, Kenji*; Kumada, Takayuki   

An influence of superfluidity on recombination reactions of H+T$$rightarrow$$HT, T+T$$rightarrow$$T$$_{2}$$ in $$^{3}$$He-$$^{4}$$He quantum media was studied under saturated vapor pressure at 1.6 K. A change of reaction mechanism was observed at transition point from normalfluid to superfluid phase. Tunneling reaction mechanism by H and T bubble atoms was proposed on the basis of large isotope effect.
