A063700100004 AUTHOR (A.Berdoz, F.Foroughi, C.Nussbaum) A063700100005 INSTITUTE (2SWTNEU) A063700100006 REFERENCE (J,JP/G,12,L133,1986) A063700100007 SAMPLE Solid target consisting of a small pastille (diameter= A063700100008 2mm and 7 mumeters thick) of polyethylene deposited onA063700100009 a self-supporting thin carbon foil. The polyethylene A063700100010 is pure to better than 0.2%. A063700100011 in order to subtract the background due to the C(p,2p)xA063700100012 reaction a carbon target (100 mu-gramm/cm-sq) was A063700100013 measured also.

A063700100016 FACILITY (CYCLO,2SWTNEU) A063700100017 METHOD (COINC) the outgoing protons. Both the forward and theA063700100018 recoil were detected in coincidence. A063700100019 (SITA) see sample A063700100020 (EXTB) the beam divergence was less than 0.1 Degree. A063700100021 ERR-ANALYS (ERR-S) errors are statistical only and include errors A063700100022 due to background subtraction and to the monitoring. A063700100023 (ERR-1) an additional common error is due to the A063700100024 normalization uncertainty. A063700100025 (EN-ERR) beam energy uncertainty. A063700100026 HISTORY (19990608C) by F.C.
