The experimental results of Deaver and Fairbank (Phys. Rev. Lett. 7, 43 (1961)), and Doll and Naebauer (ibid., p. 51), Little and Parks (ibid. 9, 9 (1962) and Phys. Rev. A133, 97 (1964)) on the penetration of a longitudinal magnetic field in a thin hollow superconducting cylinder are discussed on the basis of the Ginzburg-Landau theory. It is shown that an important role is played here by the screening factor ..mu..approx. =r/sub 1/d/delta/sub L/ /sup 2/(T) (r/sub 1/ is the inside radius of the hollow cylinder, d is the wall thickness, and delta/sub L/ (T) is the London penetration depth). It is shown that in the case ..mu..<1 the states of the cylinder are single-valued functions of the external field (there is no hysteresis). If ..mu..>1 ambiguity appears (on account of states with frozen-in flux) and hysteresis is possible. It is shown that as T..-->..T/sub c/ the hysteresis reported by Deaver and Fairbank and by Doll and Naebauer should vanish. On the other hand in the case considered by Little and Parks hysteresis may appear with increasing distance from T/sub c/. The effect of the sample resistance oscillations observed by Little and Parks in magnetic field near T/sub c/ is discussed, as is also the parabolic growth of the resistance with the field.
