The Matter Radius of 132Sn and the CREX-PREX Dilemma
J. Piekarewicz
The density dependence of the nuclear symmetry energy remains a central open problem in nuclear physics. Parity violating electron scattering experiments have provided largely mode…
Experimental study of Cr via the reaction
M. Spieker, L. A. Riley, M. Heinze +24
Excited states in Cr were studied via the Cr reaction up to the neutron-separation threshold. Proton- angular correlations and decay branching ratio…
Elucidating the role of the surface energy in density functional theory
Md Jafrul Islam, Athul Kunjipurayil, J. Piekarewicz +1
The saturation of symmetric nuclear matter -- reflected in the nearly constant interior density of heavy nuclei -- is a defining property of nuclear matter. Modern relativistic ene…
From CREX to CEvNS: The Weak Radius of 40Ar
J. Piekarewicz
Despite significant theoretical efforts, the CREX-PREX dilemma remains unresolved, preventing the reliable prediction of neutron (or weak-charge) radii that, besides their intrinsi…
Role of the isovector spin-orbit potential in mitigating the CREX-PREX dilemma
Athul Kunjipurayil, Marc Salinas, J. Piekarewicz
Pioneering electroweak measurements of the neutron skin thickness in lead-208 and calcium-48 are challenging our understanding of nuclear dynamics. Many theoretical models suggest…
Assessing the impact of uniform rotation on the structure of neutron stars
Marc Salinas, Jorge Piekarewicz
Driven by recent laboratory experiments and astronomical observations, significant advances have deepened our understanding of neutron-star physics. NICER's Pulse Profile Modeling…
