The temperature dependence of the conduction-electron-spin-resonance g value,linewidth and peak height in aluminum has been measured with a foil of 16.4 ?m, at22.6GHz, from 1.9 to IIOK. The full temperature variation of the linewidth hasbeen explained by the semiquantitative theory of Silsbee and Beuneu with ganisotropy. The orbital scattering mechanism responsible for the spin relaxation hasbeen confirmed to be different from the conventional resistivity scattering, and thephonon scattering rate has shown the temperature variation as T ' at lower tempera-lures and T' at relatively higher temperatures. The temperature variations of the gvalue and peak height have both shown nonmonotonic behavior, supporting the"two-spin model" in which electrons in second and third Brillouin zones are partiallydecoupled from one another.[conduction electron spin resonance, spin relaxation, temperature dependence, g 1[ anisotropy, Landau exchange parameter, phonon scatteringl
