Abstract The low spin states of the nucleus127Xe have been investigated with the (α, 2n) reaction by means of in-beam-γ-spectroscopy, using theosiris-cube-spectrometer at the FNTandem accelerator facility of the University of Cologne. In the negative parity system, four excited states for each of the spins 11/2−.15/2− and two 5/2−.9/2− — states could be established at excitation energies up to ≈ 1MeV above the Yrast line. With this new data, we are able to compare the non-Yrast states and their decay properties to the corresponding states of125Xe, which had been studied with similar methods in Cologne. The almost one-to-one correspondence between the states of these neighboring neutron-odd nuclei is a clear indication that their excitations at low spin remain collective well above the Yrast line.
