“…Decays of the g.s. band up to the 12 + state are visible, and the energies compare well with previous measurements [11]. In addition, unobserved lines of the rotational sequence can be identified.…”

“…Several peaks are candidates for the decay of states from the first negative-parity band, similar to the energies reported in Ref. [11]. Unfortunately, some of the observed lines are close in energy with decays of the first 2 + and 4 + states of the binary partner 134 Xe.…”

“…One type of experiments relies on the high resolving power and efficiency of a powerful γ -ray detector array to separate the γ rays from the multitude of reaction products and a tremendous background from fission [10]. A second group of measurements relies on few-nucleon transfer reactions with light oxygen beams and were successfully exploited to detect excited states, e.g., in neutron-rich 236 Th, 240,242 U isotopes [11,12]. γ rays were detected in coincidence with the outgoing transfer products.…”

Background: Nuclear structure information for the neutron-rich actinide nuclei is important since it is the benchmark for theoretical models that provide predictions for the heaviest nuclei. Purpose: γ -ray spectroscopy of neutron-rich heavy nuclei in the actinide region. Method: Multinucleon-transfer reactions in 70 Zn + 238 U and 136 Xe + 238 U have been measured in two experiments performed at the INFN Legnaro, Italy. In the 70 Zn experiment the high-resolution HPGe Clover Array (CLARA) coupled to the magnetic spectrometer PRISMA was employed. In the 136 Xe experiment the high-resolution Advanced Gamma Tracking Array (AGATA) was used in combination with PRISMA and the Detector Array for Multinucleon Transfer Ejectiles (DANTE). Results: The ground-state band (g.s. band) of 240 U was measured up to the 20 + level and a tentative assignment was made up to the (24 + ) level. Results from γ γ coincidence and from particle coincidence analyses are shown. Moments of inertia (MoI) show a clear upbend. Evidence for an extended first negative-parity band of 240 U is found. Conclusions: A detailed comparison with latest calculations shows best agreement with cranked relativistic Hartree-Bogoliubov (CRHB) calculations for the g.s. band properties. The negative-parity band shows the characteristics of a K π = 0 − band based on an octupole vibration.

“…In the present work, we employed an in-beam γ -ray spectroscopic method to investigate higher spin states of 187 W populated in an 18 O-induced one-neutron transfer reaction. This type of experimental technique is effective for the investigation of near-yrast structure in moderately neutron rich nuclei [8][9][10][11][12][13].…”

Modest spin states in neutron-rich 187 W have been populated by using a 186 W( 18 O, 17 O) one-neutron transfer reaction. Negative-parity bands previously known are extended to higher spin, and two positive-parity bands are newly identified. Configurations based on ν i 13/2 orbitals are assigned to these bands from an analysis of the level energy systematics as well as the g factors derived from in-band branching ratios.
