Equation of State of Al Based on the Thomas-Fermi Model

A wide‐range semiempirical equation of state for aluminum applicable both at near‐normal conditions and in dense plasma is presented. The finite‐temperature Thomas–Fermi model is used for the thermal contribution of electrons thus diminishing the number of fitting parameters and giving information a...

Zusammenfassung:A wide‐range semiempirical equation of state for aluminum applicable both at near‐normal conditions and in dense plasma is presented. The finite‐temperature Thomas–Fermi model is used for the thermal contribution of electrons thus diminishing the number of fitting parameters and giving information about a mean ion charge. The constructed equation of state agrees with majority of available shock‐wave data (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
