The “High-Foot” platform manipulates the laser pulse-shape coming from the National Ignition Facility laser to create an indirect drive 3-shock implosion that is significantly more robust against instability growth involving the ablator and also modestly reduces implosion convergence ratio. This strategy gives up on t…

Radiative strength functions (RSFs) for the $^{56,57}\mathrm{F}\mathrm{e}$ nuclei below the separation energy are obtained from the $^{57}\mathrm{F}\mathrm{e}(^{3}\mathrm{H}\mathrm{e},\ensuremath{\alpha}\ensuremath{\gamma})^{56}\mathrm{F}\mathrm{e}$ and $^{57}\mathrm{F}\mathrm{e}(^{3}\mathrm{H}\mathrm{e},^{3}\mathrm{H…

The electric dipole strength distribution in $^{120}\mathrm{Sn}$ between 5 and 22 MeV has been determined at the Research Center for Nuclear Physics, Osaka, from polarization transfer observables measured in proton inelastic scattering at ${E}_{0}=295$ MeV and forward angles including ${0}^{\ensuremath{\circ}}$. Combi…

We report a measurement of the parity-violating asymmetry in fixed target electron-electron (M\o{}ller) scattering: ${A}_{\mathrm{PV}}=[\ensuremath{-}175\ifmmode\pm\else\textpm\fi{}30(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}20(\mathrm{syst})]\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}9}$. This first direc…

In an experiment with the BigRIPS separator at the RIKEN Nishina Center, we observed two-proton (2p) emission from ^{67}Kr. At the same time, no evidence for 2p emission of ^{59}Ge and ^{63}Se, two other potential candidates for this exotic radioactivity, could be observed. This observation is in line with Q value pre…

We perform a study of ${}^{16}\mathrm{O}+{}^{16}\mathrm{O}$ fusion at above and below the interaction barrier energies using three-dimensional time-dependent Hartree-Fock (TDHF) calculations at above-barrier energies and density-constrained TDHF calculations for the entire energy range. We discuss the variations of th…

An analysis of the $^{12}\mathrm{C}$($^{12}\mathrm{C}$,$3\ensuremath{\alpha}$)$^{12}\mathrm{C}$ reaction was made at beam energies between 82 and 106 MeV. Decays to both the ground state and the excited states of $^{8}\mathrm{Be}$ were isolated, allowing states of different characters to be identified. In particular,…

Nuclear clustering describes the appearance of structures resembling smaller nuclei such as alpha particles (^{4}He nuclei) within the interior of a larger nucleus. In this Letter, we present lattice Monte Carlo calculations based on chiral effective field theory for the ground states of helium, beryllium, carbon, and…

We measure the effects of transverse wakefields driven by a relativistic proton bunch in plasma with densities of 2.1×10^{14} and 7.7×10^{14} electrons/cm^{3}. We show that these wakefields periodically defocus the proton bunch itself, consistently with the development of the seeded self-modulation process. We show th…

We systematically investigate the influence of nuclear deformations on the $\ensuremath{\alpha}$-decay half-lives of the deformed medium, heavy, and superheavy nuclei for $106\ensuremath{\leqslant}A\ensuremath{\leqslant}273$ and $52\ensuremath{\leqslant}Z\ensuremath{\leqslant}110$ from the ground state to ground state…
