Abstract
Statistical mechanics of a one-dimensional system of bosons with repulsive delta-function interaction is studied. Explicit calculations of the partiti on function and the cluster integrals are carried out. The results coincide with those by the thermal Bethe ansatz (TBA) method. Thermodynamic quantit ies such as the pressure, the chemical potential and the energy are given b oth for large and small coupling limits.
