Abstract:
Low-spin states of 131La have been reinvestigated via the 115In +20Ne reaction at 95 MeV with a pulsed beam and γ-ray spectroscopy. A doublet of excited states, 1/2+ at 230.3 keV and 7/2+ at 231.2 keV, has been definitely established in 131La. Low-spin state systematics in Z=57 and N=74 isotopes are presented and discussed.
