| Popis: | The direct reconstruction of the neutron-proton elastic-scattering amplitudes was carried out at six energies from 0.80 to 1.1 GeV. At the five highest energies the complete sets of spin-dependent observables used were measured in the nucleon-nucleon experimental program at SATURNE II. At 0.80 GeV, LAMPF data were also used. The invariant amplitudesa,b,c,d, ande were fit to the experimental data using a least-squares method. A search for solutions starting from random initial values was performed to determine different possible sets of amplitudes. The real and imaginary parts at several angles are listed in tables and compared with the predictions of two phase shift analyses. |
