Deeply bound levels in kaonic atoms

High-spin states have been populated in 114 45Xe via the 58Ni(58Ni, 2p) reaction at 210 MeV, using the JUROSPHERE gamma-ray spectrometer to record gamma-ray coincidences. The known level scheme has been significantly extended and includes two positive-parity and three negative-parity structures. At the highest spins, one of the negative-parity bands becomes yrast and shows the characteristics of a smoothly terminating band. Quadrupole moments for two of the bands at high spin have been estimated through a Doppler-broadened lineshape analysis; the terminating band has a reduced quadrupole moment implying that it is not far from full termination into a noncollective oblate state. Extracted B(E1) strengths are discussed in terms of possible octupole collectivity.
