PREDISSOCIATION OF HYDROGEN IN THE 3pπ D 1Π + u AND 4pσ B ″ 1Σ + u STATES

运用量子亏损理论，并与参考系变换及本征通道Ｒ矩阵法相结合，建立了描述氢分子里德伯态的预解离过程的理论方法．通过对氢分子的３ｐπＤ１Π＋ｕ和４ｐσＢ″１Σ＋ｕ电子态的预解离过程的研究，阐明其解离的机理，并给出预解离的线宽．

The predissociation of H 2 in its Rydberg states has been studied using the multichannel quantum defect theory,combined with the frame transformation and the non iterative eigenchannel R matrix method.The predissociation line positions and the widths are calculated for 3pπ D 1Π + u( v=3,J=1,2 ) and 4pσ B ″ 1Σ + u( v=2,J=1,2 ) levels.The predissociation mechanisms are discussed.
