XeKrの高リュードベリ状態におけるイオンコアスイッチング

The OODR mass spectroscopy is applied to investigate dynamical properties of Xe**Kr in high Rydberg states. It is found that two dissociation pathways producing both the Xe** and Kr** fragments compete, where the ion core of high Rydberg molecule switches. It is revealed that ion-core switching (ICS) occurs because of the interaction between bound potentials of high Rydberg states Xe**Kr and a repulsive potential of XeKr**. Moreover, the observed variation in ICS ratio is explained by the population transfer from high Rydberg states of Xe**Kr of the A ion core to those of the X ion-core.

We observed high-lying (n>238) Rydberg states which survived from strong field interaction of atoms and molecules with electron and ion coincidence detection. The high-lying Rydberg states are measured through field ionization with weak DC fields.
