Decay of mass-separated /sup 143/Ba to levels in /sup 143/La

The decay of mass-separated /sup 143/Ba to levels in /sup 143/La has been investigated using ..gamma..-ray spectroscopy in both the singles and coincidence modes. Of 69 ..gamma.. rays ascribed to the decay of /sup 143/Ba, 59 were placed in a level scheme which represents the first information on excited states in /sup 143/La. A total of 19 levels up to a maximum energy of 2347 keV were observed. The resulting level scheme is compared with that of /sup 141/La and systematics of odd-A La isotopes are discussed.
