Physics Faculty Research and Scholarship

Resonantly enhanced multiphoton ionization via the EF ¹Σ_g⁺, v′ = 6 double-well state has been used to probe the energy region below the third dissociation limit of H₂ where several high vibrational levels of the 4¹Σ_u⁺ state are expected. Theoretical ab initio potential energy curves for this state predict a deep inner well and shallow outer well where vibrational levels above v = 8 are expected to exhibit the double-well character of the state. Since the 4¹Σ_u⁺ state has f-state character, transitions to it from the …
