Abstract High spin states in153Er have been populated in the144Sm(12C, 3n)133Er reaction. Excitation functions, lifetimes, angular distributions,γ-γ coincidences and internal conversion coefficients were measured. Three isomeric states at 2.75 MeV (T 1/2=400 ns), 2.95 MeV (T 1/2∼10 ns) and 5.2 MeV (T 1/2=200 ns) have been observed. A fourth isomer seems to be weakly excited above 6.8 MeV. The level scheme proposed is discussed in term of the nuclear shell model.
