Whereas a nonrelativistic distorted wave model fails to quantitatively describe analyzing power data for exclusive proton-induced proton-knockout from the 3s_{1/2} state in Pb-208 at 202 MeV, the corresponding relativistic prediction provides a perfect description, thus suggesting that the Dirac equation is the more appropriate underlying dynamical equation. We check the consistency of this rsult by comparing predictions for both dynamical models to new high resolution data for 3s_{1/2} knockout in Pb-208 at a higher incident energy of 392 MeV.
The proton drip-line nucleus 17Ne is investigated experimentally in order to determine its two-proton halo character. A fully exclusive measurement of the 17Ne(p,2p)16F->15O+p quasi-free one-proton knockout reaction has been performed at GSI at aroun
We study the evolution of the eep cross section on nuclei with increasing asymmetry between the number of neutrons and protons. The calculations are done within the framework of the nonrelativistic and relativistic distorted-wave impulse approximatio
The isoscalar $pn$ pair is expected to emerge in nuclei having the similar proton and neutron numbers but there is no clear experimental evidence for it. We aim to clarify the correspondence between the $pn$ pairing strength in many-body calculation
We develop a fully relativistic DWIA model for photonuclear reactions using the relativistic mean field theory for the bound state and the Pauli reduction of the scattering state which is calculated from a relativistic optical potential. Results for
The two-proton knockout reaction 9Be(26Ne,O2p) was used to explore excited unbound states of 23O and 24O. In 23O a state at an excitation energy of 2.79(13) MeV was observed. There was no conclusive evidence for the population of excited states in 24O.
