We have used the perturbation theory to calculate the energy bands of the bipolaron and the free-polaron, in order to investigate the stabilities of the singlet and the triplet bipolaron states. By analyzing the specific heat and the magnetic susceptibility, we illustrate the importance of the triplet bipolaron state in understanding the experimental data.
