The geometrical factor, namely, source 11432001 17 detector distance, was held constant and equal to 11432001 18 three meters for all the measurements. 11432001 19 HISTORY (19760715T) Translated from SCISRS 11432001 20 (19820813A) converted to reaction formalism 11432001 21 (20131203A) BP:Updated to new date formats,lower case. 11432001 22 Corrections according last EXFOR rules and Dict. 11432001 23 Updated all subentries, digitized Figs. 3,9. 11432001 24 (20230527A) OS.
