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…

For more than a century the study of optical-resonance collision shifts in thermal atomic vapors has provided a window into atom/atom and atom/molecule interactions at low energies (i.e., ~ 30 meV). Overall, the agreement between theory and experiment has been good, suggesting that an understanding of these interactio…

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…

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…

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…

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…

Double photoionization accompanied by loss of $n$ C atoms ($n=0$, 2, 4, 6) was investigated by merging beams of Xe@C${}_{60}^{+}$ ions and synchrotron radiation and measuring the yields of product ions. The giant $4d$ dipole resonance of the caged Xe atom has a prominent signature in the cross section for these produc…

We used the $^{16}\mathrm{O}$${(}^{3}$He,n${)}^{18}$Ne, $^{12}\mathrm{C}$${(}^{12}$C${,}^{6}$He${)}^{18}$Ne, and $^{20}\mathrm{Ne}$(p,t${)}^{18}$Ne reactions to study $^{18}\mathrm{Ne}$ states up to an excitation energy of 10 MeV, with emphasis on levels corresponding to $^{14}\mathrm{O}$(\ensuremath{\alpha},p${)}^{17…

In solids, high harmonic radiation arises from the subcycle dynamics of electrons and holes under the action of an intense laser field. The strong-field regime opens new opportunities to understand and control carrier dynamics on ultrafast time scales, including the coherent dynamics of quasiparticles such as massless…
