| Research Abstract |
To examine the low-temperature quantum state of dilute 3He adsorbed in straight nanochannels coated with 4He film, a pulsed NMR measuring system was arranged, and the susceptibility and nuclear relaxation were measured on the dilute 3He. Obtained results such as density dependence of the Fermi temperature and density of states strongly suggest that very dilute 3He less than 0.7% coverage falls into the degenerate state at low temperatures, as a genuine one-dimensional fluid with a degree of motional freedom only along the channel axis. From nuclear relaxation measurements on pure 3He film in the nanochannels, microscopic information on atomic motion in the film, including rapid interlayer particle exchange which has not been recognized so far, was newly obtained.
