F. Grasbon et al., Signatures of symmetry-induced quantum-interference effects observed in above-threshold-ionization spectra of molecules - art. no. 041402, PHYS REV A, 6304(4), 2001, pp. 1402
We report on an experimental observation of the qualitative signatures of s
ymmetry-induced quantum-interference effects in above-threshold-ionization
spectra of O-2 (antibonding pi (g) symmetry) and N-2 (bonding sigma (g) sym
metry). It confirms the corresponding predictions of intense-field S-matrix
theory.
