“…It is especially important in reactions involving radioactive nuclear beams [27,28,29,30,31,32,33], and has been used for many decades in low energy nuclear collisions to study nuclear structure [34]. However, nuclearinduced processes may also contribute to the reactions being studied.…”

Moving highly-charged ions carry strong electromagnetic fields that act as a field of photons. In collisions at large impact parameters, hadronic interactions are not possible, and the ions interact through photon-ion and photon-photon collisions known as ultra-peripheral collisions (UPC). Hadron colliders like the Relativistic Heavy Ion Collider (RHIC), the Tevatron and the LargeHadron Collider (LHC) produce photonuclear and two-photon interactions at luminosities and energies beyond that accessible elsewhere; the LHC will reach a γp energy ten times that of the Hadron-Electron Ring Accelerator (HERA). Reactions as diverse as the production of antihydrogen, photoproduction of the ρ 0 , transmutation of lead into bismuth and excitation of collective nuclear resonances have already been studied. At the LHC, UPCs can study many types of 'new physics.'

“…In our approach the nuclear states of interest are excited and aligned by intermediate-energy Coulomb excitation [13]. The nucleus is then subjected to the transient field in a higher velocity regime than has been used previously for moment measurements, which causes the nuclear spin to precess.…”

Shell structure underlying the evolution of quadrupole collectivity in 38 S and 40 S probed by transient-field g-factor measurements on fast radioactive beams. AbstractThe shell structure underlying shape changes in neutron-rich nuclei between N = 20 and N = 28 has been investigated by a novel application of the transient field technique to measure the firstexcited state g factors in 38 S and 40 S produced as fast radioactive beams. Details of the new methodology are presented. In both 38 S and 40 S there is a fine balance between the proton and neutron contributions to the magnetic moments. Shell model calculations which describe the level schemes and quadrupole properties of these nuclei also give a satisfactory explanation of the g factors. In 38 S the g factor is extremely sensitive to the occupation of the neutron p 3/2 orbit above the N = 28 shell gap as occupation of this orbit strongly affects the proton configuration.The g factor of deformed 40 S does not resemble that of a conventional collective nucleus because spin contributions are more important than usual.

“…They are proportional to the square of the reduced transition matrix elements and can be measured via, e.g., Coulomb-excitation [1] and (γ, γ ) [2] experiments, directly. However, these techniques are selective to dipole and quadrupole excitations from the ground state.…”

In this article a method for lifetime measurements in the sub-picosecond regime via the Doppler-shift attenuation method (DSAM) following the inelastic proton scattering reaction is presented. In a pioneering experiment we extracted the lifetimes of 30 excited low-spin states of 96 Ru, taking advantage of the coincident detection of scattered protons and de-exciting γ-rays as well as the large number of particle and γ-ray detectors provided by the SONIC@HORUS setup at the University of Cologne. The large amount of new experimental data shows that this technique is suited for the measurement of lifetimes of excited low-spin states, especially for isotopes with a low isotopic abundance, where (n, n γ) or -in case of investigating dipole excitations -(γ, γ ) experiments are not feasible due to the lack of sufficient isotopically enriched target material.
