One-proton emission from the $^{102}$Sb nucleus is discussed, assuming an inert $^{100}$Sn core and the valence proton and neutron. There are experimentally measured bound states in the $^{100}$Sn-neutron system, whereas no particle-bound…

We investigate emission of the bremsstrahlung photons in the scattering of protons off nuclei at the $\Delta$-resonance energy region. Including properties of $\Delta$-resonance in the nucleus-target to the bremsstrahlung model, we find the…
