Sažetak
Background: Spectroscopic information in the neutron-rich actinide region are important to test theory in order to make predictions for the heaviest nuclei. Purpose: Gamma-ray spectroscopy of neutron-rich heavy nuclei in the actinide region. Method: Multinucleon-transfer reactions in 70Zn+238U and in 136Xe+238U have been measured in two epxeriments performed at INFN Legnaro, Italy. In the 70Zn experiment the high resolution HPGe Clover Array (CLARA) coupled to the magnetic spectrometer PRISMA was employed. In the 136Xe experiment the high-resolution Advanced Gamma Tracking Array (AGATA) was used in combination with PRISMA and the DANTE MCP detectors. Results: The ground-state band of 240U was measured up to the 24+ level. Results from a gamma-gamma coincidence and from particle coincidence are shown. Moments of inertia show clear upbend. Intriguing evidence for an extended first negative-parity band of 240U is found. Conclusions: Detailed comparison with latest calculations show best agreement with cranked relativistic Hartree-Bogoliubov (CRHB) for the g. s. band properties. The negative-parity band shows the characteristics of a band based on an octupole vibration.
