Abstract
Both long- and short-period oscillations have been seen in the conductivity of tin with a large magnetic field applied along the axis. The measurements were made at 1.4°K by means of helicon propagation in fields up to 125 kG. The results agree with calculations based on a Kubo formulation due to Chambers if phase coherence is taken as complete around small orbits and partial around large orbits. The zone oscillations predicted by Pippard were not observed.
