| Keywords | Deformations; star product; Minkowski spacetime | ||||
| Abstract | We present a deformation of the Minkowski space as embedded into the conformal space (in the formalism of twistors) based in the quantum versions of the corresponding kinematic groups. We compute explicitly the star product, whose Poisson bracket is quadratic. We show that the star product although defined on the polynomials can be extended differentiably. Finally we compute the Eucliden and Minkowskian real forms of the deformation. | ||||

| Title | Octupole correlations in the N = Z+2=56 110Xe nucleus | Type | Journal Article | ||
| Year | 2024 | Publication | Physics Letters B | Abbreviated Journal | Phys. Lett. B |
| Volume | 848 | Issue | Pages | 138371 - 7pp | |
| Keywords | Octupole deformations; Xe-110; N = Z=56 region; Fusion evaporation reactions | ||||
| Abstract | This letter reports on the first observation of an octupole band in the neutron-deficient (N = Z + 2) nucleus Xe-110. The Xe-110 nuclei were produced via the Fe-54(Ni-58,2n) fusion-evaporation reaction. The emitted gamma rays were detected using the jurogam 3 gamma-ray spectrometer, while the fusion-evaporation residues were separated with the MARA separator at the Accelerator Laboratory of the University of Jyv & auml;skyl & auml;, Finland. The experimental observation of the low-lying 3(-) and 5(-) states and inter-band E1 transitions between the ground-state band and the octupole band proves the importance of octupole correlations in this region. These new experimental data combined with theoretical calculations using the symmetry-conserving configuration-mixing method, based on a Gogny energy density functional, have been interpreted as an evidence of enhanced octupole correlations in neutron-deficient xenon isotopes. | ||||
