The first evidence for excited states in is presented. is the heaviest Tz=1/2 nucleus for which gamma-rays have been identified. The reaction ( , 1p2n) was used in the experiment, which resulted in the assignment of three gamma-rays to . A detector system consisting of the detector arrays Euroball, Neutron Wall and Euclides was used to detect gamma-rays, neutrons and charged particles, respectively.
