Electron Spin Resonance in Antimony

Electron spin resonance of conduction electrons in antimony has been investigated at 34.3 kMc/sec and 1.5°K. The results were consistent with the theory of Cohen and Blount for the $g$ factor of conduction electrons in Bi and Sb. The principal axes of the $g$ tensor coincided with those of the tilted-ellipsoidal Fermi surface. The parameters of the electron spin resonance were determined to be $g_1=3.4\mathrm{}$, $g_2=29.5\mathrm{}$, $g_3=3\mathrm{}$. Resonance was also observed from transitions that involved both an orbital transition and a Zeeman transition.
