摘要：

The uppermost quasibound rovibrational levels of the B 1-PI-u state of Na2 were accessed in a molecular beam experiment using a three step excitation scheme with Frank-Condon pumping and spatially separated laser fields to minimize line profile distortions by nonresonant multi-quantum effects. Level energies and widths due to tunneling are measured accurately. The potential function is directly derived in a fully quantal calculation fitting simultaneously all existing data, levels and widths, on the B state. This approach is superior to the conventional Dunham analysis and needs no more adjustable parameters than the other if a large body of data is involved.
