β¦ Synopsis
The results of the magneto-reflection experiments in pyrolytic graphite carried out at low temperatures in the photon energy range 0.06<hw/2x<0.50 eV and in the magnetic field range O<H<llO kG have been interpreted in terms of the Slonczewski-Weiss band model. Interband transitions associated with point H in the Brillouin zone yield the parameters y. and IAl, while the other set of interband transitions (about point K) yields values for yr, 73, and y4. The de Haas-van Alphen measurements provide the additional information required to complete the band parameter determination. Using the band parameters obtained by this method, a model of the Fermi surface of graphite has been constructed.

Neu! Y&Z). In extension of the work of Delhaes and Hisiyama\* measurements of specific heat in the range @5-5Β°K were carried out on soft carbons heattreated in the range 6~)-1600Β°C. A largp increase in the linear component with decrease in HTT is observed as well as also in the cubic component. The
