Tensor analyzing powerAyyfordpbreakup in the symmetric constant relative energy configuration

Abstract

The tensor analyzing power A in the symmetric constant relative energy geometry for the dp breakup reaction has been calculated using solutions of the three-nucleon Faddeev equations based on the Argonne AV14, AV18, Bonn-B, Nijm78, Nijm93, NijmI, NijmII, and Paris potentials, as well as the Bonn-B potential in conjunction with the Tucson-Melbourne three-nucleon interaction. The comparison with recent dp data at Fd =94.5 MeV revealed a clear discrepancy in the region where the data exhibit a pronounced structure which is not present in the theoretical results.PACS number(s): 21.45.+v, 24. 10.i, 25. 10.+s

“…The present work with tensor-polarized deuterons was motivated mainly by discrepancies between theoretical predictions and data found in the observable A yy at incoming deuteron energies 94.5 [21] and 52.1 MeV [22]. Besides, breakup tensor analyzing powers have been measured only rarely and showing the area of the (true+random) events C(tr+r) marked in white as well as the area of the randomly distributed events C(r) marked in black.…”
