Possibility of choosing between different types of nucleon-nucleon interaction on the basis of data on hard bremsstrahlung in the process pp -> pp gamma at beam energies in the range 350-500 MeV
Va. Knyr et al., Possibility of choosing between different types of nucleon-nucleon interaction on the basis of data on hard bremsstrahlung in the process pp -> pp gamma at beam energies in the range 350-500 MeV, PHYS ATOM N, 63(11), 2000, pp. 1895-1902
Previously reported results on the differential cross sections for the proc
ess pp --> pp gamma occurring at beam-proton energies of 280, 350, and 450
MeV and involving the emission of hard photons are supplemented with the re
sults of calculations at 400 and 500 MeV. The emerging pattern suggests tha
t, in the energy range E-0 = 450-500 MeV, an experiment detecting hard phot
ons from this reaction, in which case outgoing protons escape at small angl
es on the different sides of the beam direction, will be very sensitive to
the type of nucleon-nucleon potential (meson-exchange potentials versus the
Moscow potential). The energy of Eo = 400 MeV is not optimal for this purp
ose because the sensitivity is higher even at Eo = 350 MeV. The possibility
of distinguishing between the types of nucleon-nucleon potentials through
examining the transverse analyzing power A(y)(theta (gamma)), which reflect
s the correctness of Laking into account spin effects, is studied. This ana
lyzing power is found to exhibit comparatively small changes in response to
introducing short-range oscillations in the S and P waves instead of the r
epulsive-core-induced vanishing of the wave function at small distances. (C
