Abstract

The scaling behaviour s^-11 of the cross section of the reaction γd-> pn observed at SLAC and Jlab at energies E_γ=1-4 GeV and large p_T most likely displays quark degrees of freedom in the deuteron. We show that the cross sections of the dd->3Hp and pd-> 3Hen reactions measured at SATURNE follow the scaling regime s-22 at T_d= 0.5 -1.2 GeV and θ_cm=50^∘-60^∘. A necessity to get new data on this and other exclusive reactions is argued.
