Abstract: (Elsevier)

High-spin states have been located in 153 Sm by means of the (α, 3 He) reaction with 40 MeV α-particles. The scattered particles were momentum-analysed in a QMG 2 magnetic spectrometer and recorded in a position-sensitive detector. Several high-spin states were observed below 2 MeV of excitation. Strongly populated levels at 698, 1118 and 1708 keV can most likely be interpreted as 13 2 + states. The deduced nuclear structure factors and the energy location of these levels are compared with the neighbouring isotope 151 Sm and with a particle-rotor-model calculation of the i 13 2 spectra.
