Rotation Induced Octupole Correlations in the Neutron-deficient 109Te Nucleus

Research output: Contribution to journalLetter

Abstract

High spin states in the neutron deficient nucleus Te-109 have been populated with the Ni-58 + Fe-54 reaction at 220 MeV and investigated through gamma-spectroscopy methods at the GASP spectrometer making use of reaction channel selection with the ISIS Si-ball. The level scheme has been extended up to an excitation energy of approximate to 12.1 MeV. The spins and parities of the observed levels are assigned tentatively supporting the identification of two bands of opposite parity connected by strong dipole transitions inferred to be of El character. Octupole correlations in Te-109 induced by rotation are suggested as the cause of this effect. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
