The Beth-Uhlenbeck formula is rederived using the notion of symmetrized and anti-symmetrized partition function introduced by Lee and Yang. By applying the method of complex angular momentum the summation of the phase shifts appearing in the formula is converted into an integral form. Consequently, the Regge pole is introduced to obtain the exact representations of the second virial coefficients. From these representations it can be seen that the location of the resonance is subject to the statistics of the system, even when the same intermolecular potential is taken. An approximation is made to derive a simplified formula which enables us to see the resonance effects for a dilute gas of low temperature.
