摘要：
MCM-41 is a unique mesoporous material with cylindrical-like pores that provide an ideal platform to study 1D properties of adsorbed atoms(Boninsegni and Moroni in J Low Temp Phys 118(1):1, 2000). In this research, we use pulsed NMR to measure the nuclear spin-lattice relaxation times (T1) of 3He adsorbed onto 4He-preplated MCM-41 over a wide range of temperatures for a line density that would lead to a Fermi temperature of 200mK. The temperature dependence of the nuclear spin-lattice relaxation time for 0.025<T<3.5K exhibited a pronounced peak at 195mK, qualitatively similar to that calculated for the spin relaxation of 1D Fermi systems.
