We consider magnetic oscillations of resistivity of a clean hollow cylinder with fluctuating radius R, threaded by magnetic flux Φ. We demonstrate, that for very weak fluctuations ΔR≪ pF-1 the oscillations have a standard period 2Φ0 (where Φ0=πcℏ/2e), characteristic for oscillations in a clean system, while for ΔR≫ pF-1 they become Φ0-periodic, which was expected only for dirty systems with R≫ l. The work is motivated by observation of predominantly Φ0-periodic magnetic oscillations in very clean Bismuth wires.
