The geometrical factor, namely, source 1143200100017 detector distance, was held constant and equal to 1143200100018 three meters for all the measurements. 1143200100019 HISTORY (19760715T) Translated from SCISRS 1143200100020 (19820813A) converted to reaction formalism 1143200100021 (20131203A) BP:Updated to new date formats,lower case. 1143200100022 Corrections according last EXFOR rules and Dict. 1143200100023 Updated all subentries, digitized Figs. 3,9. 1143200100024 (20230527A) OS.
