The cross section asymmetry Z of the deuteron photodisintegration process d(y. pn) has been measured in the energy range 0.3-1.0 GeV for proton c~ angles of 45, 60, 75 and 90". n e data obtained are compared with predictions of the existing theoretical models, based on the conventional approach, as well as with the results of Kharkov multipole analysis which takes into account the contribution of dibaryon resonances. Neither of these theoretical models describes the experimental data satisfactorily.

The cross section asymmetry Σ has been measured for the photoproduction of π • -mesons off protons, using polarized photons in the energy range E γ = 0.5 − 1.1 GeV. The CM angular coverage is θ * π = 85 • − 125 • with energy and angle steps of 25 MeV and 5 • , respectively. The obtained Σ data, which cover the second and third resonance regions, are compared with existing experimental data and recent phenomenological analyses. The influence of these measurements on such analyses is also considered.
