Abstract
The adiabatic tension coefficient of resistance of single antimony crystals has been determined for various orientations. Since antimony crystals have the same type of symmetry as bismuth, the curves connecting the coefficient with the primary and secondary orientations have the same general shape as in the case of bismuth and again uphold the theory put forth by Bridgman. The observed values of the coefficients for antimony when the tension and current are parallel to the trigonal axis and perpendicular to it are different both in magnitude and in sign, whereas in the case of bismuth the two were both negative and very nearly equal in magnitude. The six coefficients necessary completely to determine the behavior of the resistance when deforming forces are applied to the antimony crystals have been found (1) without correcting for strain and (2) correcting for the changes arising from the strain produced by the tension.
