Abstract
The energy of the Ar trimer has been investigated in terms of the temperature for T ≤ 1 K, by means of a path-integral Monte Carlo calculation and a variational approximate method based on the use of the interparticle distances. The comparison reveals that the values of the energy obtained via both methods are in a fairly good agreement.
