Outline of Final Research Achievements |
An in-ring predissociation spectroscopy of N2O+ molecular ions, A2Σ+←X2Π2/3 (000)-(200), has been carried out in the RIKEN Cryogenic Electrostatic ring (RICE). With the use of a dedicated detection system, rotational spectra of N2O+ were observed at different storage periods of from 250 microseconds to about 1 second. The real-time observation of rotational population distribution was successfully attained, and the change of rotational temperature was measured by comparing the experimental result to numerical simulations using the pgopher code.
