High-spin states in {sup 152}Er have been populated through the {sup 116}Sn({sup 40}Ar,4{ital n}){sup 152}Er reaction. Prompt and delayed {gamma}-{gamma}-{gamma}-{ital t} and {gamma}-{ital e}-{ital t} coincidences have been measured. Levels and transitions are assigned up to an excitation energy of 15 MeV and spin and parities up to 28{sup +} at 9.7 MeV. A new isomer ({ital t}{sub 1/2}=11(1) ns) has been observed at 13.4 MeV. The results are discussed in comparison with neighboring nuclei and with shell-model calculations.
