Abstract
Finite size calculation up to 18 spins combined with the extrapolation to the thermodynamic limit is performed to obtain thermodynamic properties of spin 1/2 triangular antiferromagnet. It shows that both of isotropic and Ising-like Heisenberg systems are in quantum spin fluid state at low temperatures with the singlet ground state. In contrast with the classical system, the result is consistent with the picture that the sublattice ordering has no relevance and no phase transition occurs.
