✦ Synopsis

The theoretical expressions for the pressure and the energy of a quantum system expanded in a powerseries of powers of the density are discussed.

The various types of intermolecular fields: the 12-6-potential, the exp.-6-potential and the exp.-6-8-potential, which are in use to evaluate the exact theoretical expressions are compared.

At low temperatures only gaseous helium (3He and 4He) and hydrogen (Hz, D2, HD
