Excited states of the molybdenum isotopes Mo4297,99,101 have been populated in two experiments which used fusion-fission and binary grazing reactions to populate yrast states of the nuclei of interest. In the first experiment, the GASP array of escape-suppressed Ge detectors was used to detect γ rays from fusion-fission products initiated by the interaction of a 230-MeV beam of S36 ions with a thick target of Yb176.

Other Science Opportunities at the FCC-ee

The Future Circular Collider (FCC) ‘integrated programme’ consists of an initial electron-positron collider FCC-ee, which is later followed by a proton-proton collider, FCC-hh, installed in the same 91 km circumference tunnel close to CERN. Over a span of 15 years, from the mid or late 2040s through the early 2060s, the FCC-ee shall operate at centre-of-mass energies between about 90 and 365 GeV, always delivering the highest possible luminosities to four experiments, in a sustainable and energy-efficient way.

Upgrade of the PS booster-to-ISOLDE beam transfer line to facilitate an increase in proton driver energy
/ Fraser, Matthew (CERN) ; Bernardes, Ana (CERN) ; Newborough, Antony (CERN) ; del Alamo, Daniel (CERN) ; Grenier-Boley, Edouard (CERN) ; Pozzi, Fabio (CERN) ; Di Giovanni, Gian Piero (CERN) ; Corso, Jean-Pierre (CERN) ; Vollaire, Joachim (CERN) ; Ferreira Somoza, Jose (CERN) et al.
Following the successful completion of the LHC Injectors Upgrade (LIU) project, since 2021 the Proton Synchrotron (PS) Booster has served the LHC injector chain with protons at an increased kinetic energy of 2 GeV. An upgrade of the ISOLDE (Isotope Separator On-Line DEvice) facility has long been considered to produce radioactive ion beams with a higher energy proton driver beam. [...]

Evolution of the nuclear spin-orbit splitting explored via the $^{32}$Si($d$,$p$)$^{33}$Si reaction using SOLARIS
/ Chen, J. (SUSTech, Shenzhen ; Argonne) ; Kay, B.P. (Argonne) ; Hoffman, C.R. (Argonne) ; Tang, T.L. (Argonne) ; Tolstukhin, I.A. (Argonne) ; Bazin, D. (Michigan State U.) ; Lubna, R.S. (Michigan State U.) ; Ayyad, Y. (Santiago de Compostela U., IGFAE) ; Beceiro-Novo, S. (Michigan State U.) ; Coombes, B.J. (Australian Natl. U., Canberra) et al.
The spin-orbit splitting between neutron 1$p$ orbitals at $^{33}$Si has been deduced using the single-neutron-adding ($d$,$p$) reaction in inverse kinematics with a beam of $^{32}$Si, a long-lived radioisotope. Reaction products were analyzed by the newly implemented SOLARIS spectrometer at the reaccelerated-beam facility at the National Superconducting Cyclotron Laboratory. [...]

Modified in medium
/ Freeman, Sean (CERN ; Manchester U.)
The strong interaction is modifed in the
presence of nuclear matter. An experiment
has now quantifed with high precision and
accuracy the reduction of the order parameter
of the system’s chiral symmetry, which is
partially restored..

Evolution of nuclear structure in the neutron-rich Nb96,97,99 isotopes: Evidence for shape coexistence in N=58Nb99

Excited states of the neutron-rich niobium isotopes Nb96,97,98,4196,97,98,99 have been populated in two experiments which used fusion-fission and multinucleon binary grazing reactions to populate high-spin yrast states. In the multinucleon-transfer experiment, a 530-MeV beam of Zr96 ions was incident on a thin Sn124 target; projectile-like ejectiles were detected and identified using the PRISMA magnetic spectrometer and the associated γ rays were detected using the CLARA array of Ge detectors.
