【 摘 要 】

The excitation cross section for unassigned dipole forbidden autoionizing state in Rb2molecules was measured in an impact energy range from the excitation threshold at 15.55±0.07 eV up to 17.5 eV. The cross section possesses a resonance shape with the maximum value of 1.0 ± 0.5 × 10-14cm2at 0.4 eV above the excitation threshold.
