摘要: We observe energy-dependent angle-resolved diffraction patterns in protons from strong-field dissociation of the molecular hydrogen ion H_{2}^{+}. The interference is a characteristic around laser-induced conical intersection (LICI), which point contact between two surfaces dressed two-dimensional Born-Oppenheimer potential energy landscape diatomic molecule strong laser field. magnitude and angular period depend strongly on difference initial state LICI, consistent with coherent cone-shaped barrier whose width thickness relative cone apex. These findings are supported by numerical solutions time-dependent Schrodinger equation for similar experimental conditions.
