Abstract

The transitional nuclei ¹³²Xe and ¹³³Xe are investigated after multinucleon-transfer (MNT) and fusion-evaporation reactions. Both nuclei are populated (i) in ¹³⁶Xe+²⁰⁸Pb MNT reactions employing the high-resolution Advanced GAmma Tracking Array (AGATA) coupled to the magnetic spectrometer PRISMA, (ii) in the ¹³⁶Xe+¹⁹⁸Pt MNT reaction employing the GAMMASPHERE spectrometer in combination with the gas-detector array CHICO, and (iii) as an evaporation residue after a ¹³⁰Te(α,xn)^134−xnXe fusion-evaporation reaction employing the HORUS γ-ray array at the University of Cologne. The high-spin level schemes are considerably extended above the J^π=(7⁻) and (10⁺) isomers in ¹³²Xe and above the 11/2⁻ isomer in ¹³³Xe. The results are compared to the high-spin systematics of the Z=54 as well as the N=78 and N=79 chains. Furthermore, evidence is found for a long-lived (T_1/2≫1μs) isomer in ¹³³Xe which closes a gap along the N=79 isotones. Shell-model calculations employing the SN100PN and PQM130 effective interactions reproduce the experimental findings and provide guidance to the interpretation of the observed high-spin features.
