Yrast band in 122Cs

High spin states of are reinvestigated through the reaction at the beam energy of 54 MeV. Two new levels are added to the lower side of the most strongly populated band and the previously proposed 488 keV linking transition between the two observed bands is replaced by the 95 keV linking transition. As a result of these new observations, it becomes reasonable to assign the most strongly populated band in as the yrast band.
