M060100100003 AUTHOR (C.D.Bowman,C.F.Auchampaugh,S.C.Fultz) M060100100004 REFERENCE (J,PR,133,B676,1964) M060100100005 INSTITUTE (1USALRL) M060100100006 FACILITY (LINAC,1USALRL) M060100100007 METHOD (EXTB,SITA) M060100100008 ANALYSIS Direct cross section measurement. M060100100009 COMMENT The photodisintegration of 235U has been studied, M060100100010 using nearly monochromatic photons obtained from the M060100100011 annihilation in flight of fast positrons. The M060100100012 partial cross sections sigma(g,F), sigma(g,n), M060100100013 and sigma(gamma,2n) were determined. Integrated cross M060100100014 sections for these reactions were found to be 1.07, M060100100015 1.00, and 1.49 MeV*b, respectively. Structure in the M060100100016 giant resonance of the compound-nucleus-formation M060100100017 cross section was observed and from this a M060100100018 quadrupole moment of 12.8 (1.3)b was found. An M060100100019 energy dependence in the quantity width-n/width-F M060100100020 was observed. M060100100021 HISTORY (20000222C) Data were compiled at the Russia MSU SINP M060100100022 CDFE by V.Varlamov. M060100100023 (20081015A) NDS: ref. was corrected. p.676 => B676.
