Abstract

The dc Stark effect is studied for autoionising Rydberg states of H2 converging on the ν+=2 ionisation limit. The levels (n = 13–22) are excited from the ground state using a coherent XUV source (bandwidth ≈ 1 cm−1) and are strongly perturbed by the field (15–2000 V/cm). Many new states are observed, including the high-/hydrogenic manifolds. A detailed Stark map is obtained for the first time, and a matrix diagonalisation calculation of field-induced state mixing is carried out to explain some of the observed features.
