Abstract

We present measurements of the pressure derivative

\frac{d (\ln S)}{dp}

of the Fermi surface cross section

S

at [100] and [111] for the electrons in Pd and Pt in the range 0-25 atm. The results suggest that the electron pressure derivatives in these metals are nearly isotropic. Along [100]

\frac{d (\ln S)}{dp} = (4.0 \pm 0.4) \times 10^{- 4} and (3.2 \pm 0.3) \times 10^{- 4}

{kbar}^{- 1}

for Pd and Pt, respectively.
