This implies that all nuclei are spherical and their radius is directly proportional to the cube root of their volume (volume of a sphere = 4 / 3πR3). Nuclei can also exist in a deformed shape and thus a degree of deformation ,β2, can be included to take this into account. The fa...

A mA-level high-power target was developed via surface microchannel water cooling. Furthermore, using a high-purity substrate combined with ion implantation, surface plating, and filtered cathodic vacuum arc (FCVA) technologies, a high-purity isotope-enriched target was prepared, which can solve var...
Current observations, which imply that the radius of a 1.4 solar mass neutron star lies between 10.4 and 12.9 km, also imply that 43 < L < 67 MeV, where L is a parameter describing the slope of the nuclear symmetry energy and that the neutron skin thickness in lead is relatively small....
4a and found a relative error that was smaller than 0.2%. The nuclear-matter equation of state and saturation properties are computed with the CCD(T) approximation which includes doubles excitations and perturbative triples corrections. The 3N forces are considered beyond the normal-ordered two-body...
whether the nuclei have rigid triaxial shape or fluctuations ofγaround its mean value37. This issue is complicated by possible changes ofγwhen nuclei are excited38. Our three-body observable\(\langle {v}_{2}^{2}\delta {p}_{{\rm{T}}}\rangle \)in equation (2) is sensitive only to...
Here it is assumed that cosmic ray nuclei either escape as neutrons from the source (which leads to escape spectra ∝E −2), or as charged particles if they can reach the outside of the source within their Larmor radius (“direct escape”, which leads to harder escape spectra ∝E −...

The distribution of neutrons is important in determining the thickness of the neutron skin, the symmetry energy of the nucleus, the QCD equation of state (EoS) of dense nuclear matter, and astrophysical observables such as the mass–radius relationship of neutron stars and the gravitational wave ...
For this purpose, we transform the Bloch equation into spherical coordinates and provide the solutions for the polar angle ϑ, the phase φ, and the radius r, which we here define as the magnitude combined with a sign (refer to the section “Methods” for the derivation). Except in the...
