摘要：

The two lowest-lying members of the P-1(0) dipole series of autodetaching resonances in H-located just below the H(n = 2) threshold have been observed and characterized, utilizing Doppler-tuned collinear laser spectroscopy. The resonance positions have been determined for both H- and D-. allowing the first critical test of the predicted isotope effects. The experimental isotope shifts are consistent with a small specific mass shift. We interpret these results as evidence for a rather small electron momentum correlation.
