The oscillatory dependence of the resistance on the magnitude of the magnetic flux in the cross section of a specimen with period hc/2e and negative longitudinal magnetoresistance are observed in cylindrical lithium films at helium temperatures. The phase of the oscillations and the sign of the magnetoresistance are opposite to those observed for magnesium,4 which is attributed to the smallness of the spin-orbital interaction in lithium. The results agree well with the theoretical predictions.
