ITEP複合加速器施設において、0.4, 0.6, 0.8, 1.2, 1.6、及び、2.6GeVのエネルギーを持つ陽子をW及びTaの厚いターゲットに入射した場合のGd生成断面積を、スペクトロメータを用いて測定した。得られた実験データを他施設の実験結果及び、MCNPX(BERTINI, ISABELモデル), CEM03.02, INCL4.2, INCL4.5, PHITS、及び、CASCADE07コードの計算結果と比較した。2

The cross sections for the production of Gd in W and Ta targets irradiated by 0.4-, 0.6-, 0.8-, 1.2-, 1.6-, and 2.6-GeV protons at the ITEP accelerator complex have been measured by direct spectrometry without chemical separation. The experimental data have been compared with the data obtained at other laboratories and with the theoretical simulations of the yields on the basis of the BERTINI, ISABEL, CEM03.02, INCL4.2, INCL4.5, CASCADE07, and PHITS codes.
