A study of intrinsic state halflife measurements in the N=80 nucleus 138Ce has been made using the 130Te(12C,4n) 138Ce fusion evaporation reaction at beam energy of 56 MeV. The fast-timing gamma-ray coincidence method was used with a mixed LaBr 3(Ce)-HPGe array to establish the lifetimes of the yrast 6 + state at 2294 keV, the Iπ=5- state at 2218 keV, the Iπ=11+ state at 3943 keV and the 14 + state at that at 5312 keV, all of which are in the sub nanosecond regime. Reduced transition probabilities have been calculated for the electromagnetic decays from these states.
