Abstract
We utilize a two-body correlated basis function and van der Waals interaction to describe interacting bosons in the anharmonic trap. We analyze the behaviour of specific heat capacity near the transition temperature in mesoscopic region. We calculate the transition exponent to define the quasi phase transition for different anharmonicity. Comparison with pure harmonic trap is also addressed.
