Kiriyama, J. Taniguchi, M. Suzuki, T. Takagi] We consider 4He particles confined in a quasi-one-dimensional nanoscale channel in the range of liquid density, and numerically calculate the energy per particle by the imaginary time path integral Monte Carlo method. When the channel diameter becomes less than 1.6nm, T onset, at which the energy drops due to the particle exchange effect, shifts to lower temperature, and disappears below 0.48nm. The diameter dependence of T onset is similar to the behavior of the superfluid onset temperature, T o, for mesoporous materials FSM16 observed by the torsional oscillator.
