“…An independent extensive theoretical study of nuclei around mass 130 was published by Teruya et al [51]. The results include excited states and electromagnetic transition probabilities for Xe isotopes within the shell model in the gdsh model space including the 0g 7/2 , 1d 5/2 , 1d 3/2 , 2s 1/2 , and 0h 11/2 orbitals.…”

Detailed spectroscopic information on the N ∼ 82 nuclei is necessary to benchmark shell-model calculations in the region. The nuclear structure above long-lived isomers in 134 Xe is investigated after multinucleon transfer (MNT) and actinide fission. Xenon-134 was populated as (i) a transfer product in 136 Xe+ 238 U, and 136 Xe+ 208 Pb MNT reactions and (ii) as a fission product in the 136 Xe+ 238 U reaction employing the high-resolution Advanced Gamma Tracking Array (AGATA). Trajectory reconstruction has been applied for the complete identification of beam-like transfer products with the magnetic spectrometer PRISMA. The 136 Xe+ 198 Pt MNT reaction was studied with the γ-ray spectrometer GAMMASPHERE in combination with the gas detector array CHICO. Several high-spin states in 134 Xe on top of the two long-lived isomers are discovered based on γγ coincidence relationships and information on the γ-ray angular distributions as well as excitation energies from the total kinetic energy loss and fission fragments. The revised level scheme of 134 Xe is extended up to an excitation energy of 5.832 MeV with tentative spin-parity assignments up to 16 + . Previous assignments of states above the 7 − isomer are revised. Latest shell model calculations employing two different effective interactions reproduce the experimental findings and support the new spin and parity assignments.

The high-spin structures and isomers of the N = 81 isotones 135 Xe and 137 Ba are investigated after multinucleon-transfer (MNT) and fusion-evaporation reactions. Both nuclei are populated (i) in 136 Xe+ 238 U and (ii) 136 Xe+ 208 Pb MNT reactions employing the high-resolution Advanced Gamma Tracking Array (AGATA) coupled to the magnetic spectrometer PRISMA, (iii), in the 136 Xe+ 198 Pt MNT reaction employing the γ-ray array GAMMASPHERE in combination with the gas-detector array CHICO, and (iv) via a 11 B+ 130 Te fusion-evaporation reaction with the HORUS γ-ray array at the University of Cologne. The high-spin level schemes of 135 Xe and 137 Ba are considerably extended to higher energies. The 2058-keV (19/2 − ) state in 135 Xe is identified as an isomer, closing a gap in the systematics along the N = 81 isotones. Its half-life is measured to be 9.0(9) ns, corresponding to a reduced transition probability of B(E2, 19/2 − → 15/2 − ) = 0.52(6) W.u. The experimentally-deduced reduced transition probabilities of the isomeric states are compared to shell-model predictions. Latest shell-model calculations reproduce the experimental findings generally well and provide guidance to the interpretation of the new levels.

“…Three and four neutrons away from the N = 82 shell closure, the respective Xe isotopes have come within reach of advanced untruncated shell-model calculations. Several recently developed effective shell-model interactions [2][3][4][5][6][7] take aim toward a unified description of the 50 N, Z 82 region.…”

The transitional nuclei 132 Xe and 133 Xe are investigated after multinucleon-transfer (MNT) and fusionevaporation reactions. Both nuclei are populated (i) in 136 Xe + 208 Pb MNT reactions employing the highresolution Advanced GAmma Tracking Array (AGATA) coupled to the magnetic spectrometer PRISMA, (ii) in the 136 Xe + 198 Pt MNT reaction employing the GAMMASPHERE spectrometer in combination with the gas-detector array CHICO, and (iii) as an evaporation residue after a 130 Te(α,xn) 134−xn Xe 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 132 Xe and above the 11/2 − isomer in PHYSICAL REVIEW C 96, 024321 (2017) 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.
