“…The PF SA was applied to calculate form factors of various composite particles [17][18][19] with reasonable results. Our calculation of the proton-proton bremsstrahlung [20] showed that the PF SA violates the continuity equation for the NN current operator, but the violation is relatively small for the considered kinematics.…”

“…In our previous papers [20,39], we showed that the hard pp → ppγ bremsstrahlung at moderate energies (E lab 500 MeV) is critical to the kind of potential (MP versus RCP). The available experimental data at smaller energy of E lab = 280 MeV [40] give only a preliminary indication of MP validity [20]. Our present paper strengthens this line of phenomenological research using modern deuteron photodisintegration data.…”

We review a concept of the Moscow potential of the NN interaction. On the basis of this concept, we derive by quantum inversion optical partial potentials from the modern partial-wave analysis data and deuteron properties. Point-form relativistic quantum mechanics is applied to the two-body deuteron photodisintegration. Calculations of the cross-section angular distributions cover photon energies between 1.1 and 2.5 GeV. Good agreement between our theory and recent experimental data confirms the concept of deep attractive Moscow potential with forbidden S and P states.

“…It opens wide possibilities not only to investigate the isospin dependence of the meson production [3], but also to measure the Bremsstrahlung radiation created in the collisions of nucleons. The study of the latter process is interested since it is highly sensitive to the kind of the nucleonnucleon potential, and hence may serve as a tool to discriminate between various existing potential models [4,5]. Although Bremsstrahlung radiation has been studied since many years, it is still the subject of interest of many theoretical and experimental groups [4,5,6,7].…”

Due to the high sensitivity of the N N → N N γ reaction to the nucleon -nucleon potential, Bremsstrahlung radiation is used as a tool to investigate details of the nucleon -nucleon interaction. Such investigations can be performed at the cooler synchrotron COSY in the Research Centre Jülich, by dint of the COSY-11 detection system. The results of the identification of Bremsstrahlung radiation emitted via the dp → dpγ reaction in data taken with a proton target and a deuteron beam are presented and discussed.

We propose a method for reconstruction of the optical potential from scattering data. The algorithm is a two-step procedure. In the first step the real part of the potential is determined analytically via solution of the Marchenko equation. At this point we use a diagonal Pad\'{e} approximant of the corresponding unitary $S$-matrix. In the second step the imaginary part of the potential is determined via the phase equation of the variable phase approach. We assume that the real and the imaginary parts of the optical potential are proportional. We use the phase equation to calculate the proportionality coefficient. A numerical algorithm is developed for a single and for coupled partial waves. The developed procedure is applied to analysis of $^{1}S_{0}$ $NN$, $^{3}SD_{1}$ $NN$, $P31$ $\pi^{-} N$ and $S01$ $K^{+}N$ data.Comment: 26 pages, 8 figures, results of nucl-th/0410092 are refined, some new results are presente
