光学模型与ADS靶的反应截面

OPTICAL MODEL STUDIES OF REACTION CROSS SECTIONS FOR ADS TARGET MATERIAL

利用核反应中光学模型理论 ,对质子入射能量从阈能到 45 0MeV ,加速器驱动的洁净核能系统的靶材2 0 9Bi、2 0 8Pb、2 0 2 Hg、1 97Au、1 84W、1 81 Ta与质子的反应进行了研究 给出了两套与实验数据符合很好的光学势参量 ;预言了质子与Bi、Pb、Hg、Au、W、Ta的反应截面 ;

Using the optical model theory, reactions of proton induced on ADS target material 209 Bi, 208 Pb, 202 Hg, 197 Au, 184 W, 181 Ta were studied in energy region from threshold up to 450 MeV. Two sets of proton optical potential parameters for Bi, Pb, Hg and Au, W, Ta were obtained, respectively. The reaction cross sections and elastic scattering cross sections were calculated.
