Abstract
Values of the dissociation energies and the interaction constants in the long-range potential for the B 3ΠOu+ states of Br2 and Cl2 have been obtained from least-squares fits to the attractive part of the Rydberg-Klein-Rees potentials. The term in r -6 is not negligible even at large internuclear distances corresponding to the last few vibrational levels. The validity of the long-range inverse-power expansion in the internuclear distance r has been investigated. The expansion is valid outside the electron-overlap region given by in agreement with the result found in the analysis of I2.Keywords
