Measurements of the ideal electrical resistivity of single crystals of pure antimony are given in the temperature range 4.2 to 77 °K. Below 20 °K the resistivity shows a T3 dependence unlike the case of the semi‐metal Bi in which a T 2 dependence is observed. The temperature variation of the Hall coefficients from 4.2 to 30 °K is presented. The Hall coefficient R 23,1 decreases linearly with temperature from 4.2 to 20 °K whereas the coefficient R 12,3 increases monotonously from 4.2 to 20 °K. This is in contrast with the observed behaviour of these coefficients above 55 °K. The possible causes of the observed temperature dependence of the Hall Coefficients are discussed.
