摘要：

Fluorescence-excitation spectroscopy near 84.5 nm has been used to measure the threshold for the dissociation limit of H-2(B'1-SIGMA(u)+) = H(1s) + H(2s) at 118377.06 +/- 0.04 cm-1. This yields a value of D0(H-2) = 36118.11 +/- 0.08 cm-1 for the dissociation energy of the ground electronic state X(1-SIGMA(g)+) of H-2, in agreement with the latest theoretical calculation which includes nonadiabatic, relativistic, and radiative corrections. When combined with recent determinations of the ionization energy of H-2, the present D0(H-2) leads to the value D0(H-2+) = 21 379.36 +/- 0.08 cm-1, also in good agreement with theoretical values.
