Elastic and charge exchange scattering of pions on3He in the (3,3)-resonance region

Abstract: The elastic scattering of pions from 3He and the single charge exchange reaction 3He (~-,rc~ are calculated in the energy domain of the (3,3)-resonance within the framework of Glauber's theory, including spin and isospin degrees of freedom in all orders. It is pointed out that, from the first minimum on, the differential cross section strongly depends on the parametrization of the rcN amplitude, especially on its continuation into the unphysical region of momentum transfer. Single and double spin flip contri… Show more

“…For example, in the SCE reaction at T =300 MeV and at pion angles 0 & 90 basically all calculations yieM differential cross sections which fall two orders of magnitude below the data. Only calculations in the framework of the Glauber 47 941 1993 The American Physical Society approach [12,13] reached better agreement in this region. However, we concur with Ref.…”

“…The predictions of the Glauber calculation of Lohs and Mandelzweig lie closest to the data, but any apparent agreement may be fortuitous because of the nature of the Glauber approximation. Its application to pion-nucleus scattering in general is known to be doubtful, because its validity depends on a forward peaking of both the pion-nucleus and pion-nucleon amplitudes, which is not a characteristic of the latter" The prediction of elastic scattering on 3 He at large angles is also poor, 7 The modified Glauber calculation attempts to circumvent this shortcoming but this remedy, which the authors describe as "ad hoc" seems to worsen the disagreement with our CEX data.…”
