FIGURE 2.6 Multidisciplinary quest for understanding the neutron-rich matter on Earth and in the cos-mos. The study of neutron skins and the PREX experiment are discussed in the text. The anticipated discovery of gravitational waves by the Laser Interferometer Gravitational Wave Observatory (LIGO) and the allied European detector Virgo will help understanding large-scale motions of dense neutron-rich matter. Finally, advances in computing hardware and computational techniques will allow theorists to perform calculations of the neutron star crust. SOURCE: Courtesy of W.

Nuclear Masses and Radii

The binding of nucleons in the nucleus contains integral information on the interactions that each nucleon is subjected to in the nuclear environment. Dif-ferences in nuclear masses and nuclear radii give information on the binding of individual nucleons, on the onset of structural changes, and on specific interac-tions. Examples of recent measurements of charge radii in light halo nuclei were discussed above. With exotic beams and devices such as Penning and atomic traps, storage rings, and laser spectroscopy the masses and radii of long sequences of exotic isotopes are becoming available, extending our knowledge of how nuclear

Our Very Talented Fellows and Bridges

Two Amendments to the FRIB-TA Charter

Third funding cycle: June 2020 – May 2025 FRIB-TA is on its way to a steady-state scenario

Two Amendments were recently adopted

Transition to a director line: With FRIB and the FRIB-TA kicking into higher gears of activity, it was considered beneficial to transition into a director line — with the director serving a total of three years, one as director-elect, one as director, and one as past director.

FRIB-TA members from foreign institutions: FRIB-TA members from foreign institutions will be eligible to vote and one seat in the FRIB-TA executive board will be reserved for a member from a foreign institution.

Effective August 1, 2020, Jutta Escher became director and Jorge Piekarewicz past director
