92. New frontiers in collinear laser spectroscopy at COLLAPS: Shell structure in exotic Ca isotopes

Liss Vazquez Rodriguez (Max Planck Institute for Nuclear Physics)

2026-07-31, 11:00 a.m.

Invited speakers

Collinear laser spectroscopy provides high-precision access to nuclear spins, electromagnetic moments, and changes in mean-square charge radii of atomic nuclei. In this contribution, I will present an overview of recent progress at COLLAPS during CERN Run 3, with emphasis on spectroscopy of the neutron-rich calcium isotopes ${}^{53,54}\mathrm{Ca}$ and on major instrumental developments aimed...

94. Charge Radii and Magnetic Moments of Neutron-Rich Silicon Isotopes

Fabian Camilo Pastrana Cruz (Massachusetts Institute of Technology)

2026-07-31, 11:30 a.m.

This contribution will present the first laser spectroscopy measurements of neutron-rich silicon isotopes from stable 28Si up to 38Si, performed using the Resonance Ionization Spectroscopy Experiment (RISE) at the BEam COoling LAser spectroscopy (BECOLA) facility, located at the Facility for Rare Isotope Beams (FRIB). From the measured isotope shifts and hyperfine structure, we extracted the...

65. Laser-radio-frequency double-resonance spectroscopy of 209Bi for the extraction of its nuclear magnetic octupole moment

Anita Candiello (Instituut voor Kern- en Stralingsfysica, KU Leuven, 3001 Leuven, Belgium)

2026-07-31, 11:50 a.m.

Contributed Talks

Nuclear electromagnetic moments provide sensitive probes of the distribution of charge and magnetization inside the nucleus, yet higher-order moments remain largely unexplored. Current high-resolution laser spectroscopy techniques allow to achieve precisions of the order of 1 MHz [1], giving access to magnetic dipole and electric quadrupole moments. However, as the multipole order increases,...

80. Collinear Laser Spectroscopy far from stability: Mg and Cd

Anthony Roitman (McGill University)

2026-07-31, 12:10 p.m.

Contributed Talks

In recent years, significant progress in nuclear structure theory has been driven by the availability of precise experimental data on short-lived nuclei with neutron-to-proton ratios far from those at the valley of stability in the nuclear chart. Collinear Laser Spectroscopy (CLS) is a powerful technique for obtaining nuclear ground-state properties such as spins, electromagnetic moments, and...
