Abstract : The absolute de Haas-van Alphen (dH-vA) frequencies and the scaling effect of small hydrostatic pressures on extremal cross sections of the Fermi surface have been measured in freely mounted samples of K, Rb, and Cs. The dH-vA frequencies are in good agreement with those derived from currently accepted values for the low-temperature lattice constants of the three metals at (1.824 plus or minus 0.002), (1.603 plus or minus 0.003), and (1.365 plus or minus 0.002) x 10 to the 8th power G, respectively. The low-temperature compressibilities derived from the pressure measurements show discrepancies of -5, -8, and -14% with those measured by more conventional techniques. The characteristic energy B(0)V(0) (bulk modulus x atomic volume) is found to be constant. (Author)
