N2 - At the GSI Helmholtzzentrum für Schwerionenforschung GmbH (Darmstadt, Germany) intense focused beams of energetic heavy ions are used to generate high-energy-density states in matter [1]. In recent experiments, initially solid tantalum and tungsten samples (50-90 μm thick foils) were uniformly heated in a quasi-isobaric way by a microsecond ion-beam pulses. The temperature of a sample has been observed by a fast multi-channel optical pyrometer during and after the heating. The isobaric heat capacity of the melted metals as well as the enthalpy of fusion have been obtained from the temperature - enthalpy dependence, calculated from measured temperature-time data. A good measurement statistics has been achieved by carrying out a large number of the same experiments with identical targets. The obtained experimental results for liquid tantalum and tungsten heated up to 5000 K are presented and discussed.
