摘要：

A Sn-119 NMR study is presented for the gap-type valence fluctuating compound CeNiSn. No magnetic ordering is observed down to 0.1 K. The temperature and the magnetic field dependence of the nuclear spin-lattice relaxation rate, 1/T1, is well interpreted by assuming a quasiparticle band with a band width of 140 K and a very narrow pseudo-gap of 14 K at the Fermi level in which low-energy excitations are present.
