Hugoniot data for solid argon (initially at 77°K and 1 bar) and solid hydrogen (initially at 5°K and 1 bar) have been obtained to 143 kbar and 6.4 kbar, respectively, using the projectile impact method. The argon data (at volumes of 15.28, 14.84, and 14.64 cm3/mole) are in fair agreement with previous shock data, and in excellent agreement with the most recent theoretically predicted Hugoniot. The hydrogen data (at volumes of 17.10, 15.32, 15.27, 15.11 cm3/mole) are compared with Hugoniots calculated from published isothermal compression data. For both argon and hydrogen, the shock and isothermal data are self-consistent under the assumption γ/V is constant. To compressions of V/V0≈0.65, the previous isothermal compression measurements on solid hydrogen are consistent with the present shock data.
