M012200100003 AUTHOR (E.A.Kotikov,E.D.Makhnovskiy) M012200100004 INSTITUTE (4RUSFTI) M012200100005 REFERENCE (J,YF,41,289,1985) M012200100006 (J,SNP,41,183,1985) - Eng.trans.of YF,41,289,1985 M012200100007 FACILITY (SYNCH,4RUSFTI) M012200100008 INC-SOURCE (BRST) M012200100009 METHOD (EXTB,SITA) M012200100010 DETECTOR (PLATE) M012200100011 COMMENT Absolute measurements of the cross section have been M012200100012 performed for the reaction gamma+(Li-6) - p+d+t - M012200100013 21.29 MeV at energies Eg <= 30 MeV. The measurements M012200100014 were carried out by means of selection of M012200100015 corresponding three- prong stars in nuclear emulsion M012200100016 loaded with Li-6 isotope. An intensitive maximum has M012200100017 been observed in the obtained excitation function M012200100018 sigma(Eg) at an energy Eg=23.7(0.1) MeV; the total M012200100019 width at half-maximum is about 1.7 MeV. The integral M012200100020 reaction cross section for the gamma-ray energy M012200100021 interval from 22 up to 30 MeV amounts to 6.6(0.7) M012200100022 MeV*mb. The totality of the data obtained and their M012200100023 analysis indicate that the absorption of g-quanta M012200100024 with energies below 30 MeV by Li-6 nucleus leading to M012200100025 production of proton, deuteron and triton is M012200100026 explained mainly in terms of triangular feynman M012200100027 graphs with rearrangement of the nuclei at vertices M012200100028 including the virtual processes gamma+(H-3) -> n+(H- M012200100029 2), or gamma+(H-3) -> -> (He-3)+(H-2) and n+(He-3) -> M012200100030 p+(H-3). a suppression of symmetric channel into M012200100031 (n+d+He-3) are shown.
