✦ Synopsis

The (Z]"ll,+x 'z transition of Cs2 is observed in a very cold pulsed molecular beam using the resonanceenhanced twophoton ionization method. The term values ofthe substates of (2)'l&state are determined tobe T,= 14121.OkO. 1,14013.2 f 0.1, 13912.9+0. I, and 13909.4f 0.1 cm-' for the 2, l,, O,+, and 0; state, respectively. These term valuesagree well with the theoretical predictions.
