Abstract
The decay and feeding of two yrast isomer (I~26ħ and I~36ħ respectively) in 152Er is measured. The isomeric delays are used to separate the spectrum of γ-rays from the highest angular momentum states from the spectrum due to the decay of low spin states. Strong dipole as well as quadrupole radiation dominates the yrast cascades which feed into the I~36ħ isomer, and the correlation spectrum for the feeding transitions does not indicate any collective structure for spins below 50ħ. It is tentatively concluded that the near magic nucleus 152Er remains spherical or oblate up to this high spin value.
