Fig. 2From: Rydberg-Stark deceleration of atoms and moleculesHigh-resolution millimeter-wave spectra of Kr. Millimeter-wave spectra of the 77d[3/2](J ′=1)→93p[3/2](J=1) transition in Kr recorded following interaction times between the atoms and the millimeter-wave field of τ=3, 6 and 18 μs as indicated. The corresponding transition line-widths are 350, 180 and 60 kHz, respectively. From [6] with permissionBack to article page
