Temperature dependence of electrical conductivity of quasi-one-dimensional
(Q1D) electrons on helium film capillary-condensed in grooves of an optical
diffraction grating was measured. The conductivity showed a maximum near 1
.3 K and a minimum near 0.7 K. This result was quite different from that of
two-dimensional electron system and the theory for Q1D system presented so
far. A qualitative explanation for the present result was given. (C) 2000
