Abstract

We calculate the energy distribution of a dyonic dilaton black hole by using the Tolman's energy-momentum complex. All the calculations are performed in quasi-Cartesian coordinates. The energy distribution of the dyonic dilaton black hole depends on the mass, electric charge, magnetic charge and asymptotic value of the dilaton. We get the same result as obtained by Y-Ching Yang, Ching-Tzung Yeh, Rue-Ron Hsu and Chin-Rong Lee by using the Einstein's prescription.
