Abstract

Spin-dependent observables in intermediate-energy $pd$ elastic scattering within the framework of the refined Glauber model are considered. The improvements include an account of all ten $pp$ and $pn$ helicity amplitudes at respective energies constructed on the basis of modern phase-shift analysis, accurate deuteron wave functions taken from the modern $NN$ force model and account of charge-exchange effects. Predictions of the refined diffraction model for the differential cross section and analyzing powers are compared with exact three-body Faddeev calculations and the recent experimental data. An amazingly good agreement between the results of both theoretical approaches as well as between the refined Glauber model and experiment in a wide angular range not only for differential cross section but also for vector and tensor analyzing powers has been found in the first time. Possible reasons for this agreement are discussed.
