Reaction Cross Sections and -Cluster Geometry in C and Be Isotopes
Tianyu Wu, Baohua Sun, Ulf-G. Meißner +1
Reaction cross sections are widely used to infer matter radii, yet their sensitivity to nuclear structure beyond radial one-body distributions is less well understood.…
Deformation effects on reaction observables of beryllium nuclei from ab initio densities
Qi Lu, Rui-Feng Tian, Shi-Sheng Zhang +2
We combine three-dimensional intrinsic densities from ab initio nuclear lattice effective field theory with a deformed Glauber model to study high-energy reactions of {7-12}Be. To…
The anomalous long lifetime of C revealed by ab initio nuclear lattice EFT
Teng Wang, Serdar Elhatisari, Xu Feng +2
The 5730-year half-life of C, the physical basis of radiocarbon dating, is anomalously long compared to typical nuclear-physics expectations. Its origin has remained a subje…
Nuclear Charge Radius of Be from Muonic Atom Spectroscopy Using a Microcalorimeter
Ofir Eizenberg, Shikha Rathi, Andreas Abeln +34
The authors measured the 2p→1s transition energy in muonic 9Be with a metallic magnetic calorimeter, obtaining a nuclear charge radius of 2.5506 fm with unprecedented precision, su…
Full Uncertainty Quantification of Sign-Problem-Free Quantum Monte Carlo Methods and Nuclear Lattice Effective Field Theory Benchmarks
Zhong-Wang Niu, Bing-Nan Lu, Shuang Zhang +4
Sign-problem-free quantum Monte Carlo (QMC) methods provide one of the few polynomial-scaling routes to controlled, nonperturbative benchmarks of medium-mass and heavy nuclei. We p…
Elastic deuteron-deuteron scattering within Nuclear Lattice Effective Field Theory
Helen Meyer, Serdar Elhatisari, Fabian Hildenbrand +1
We calculate low-energy deuteron-deuteron scattering in the spin-quintet channel using nuclear lattice effective field theory. The calculation combines chiral interaction…
