0.04から2.6GeVのエネルギーを持つ陽子を$$^{93}$$Nb及び$$^{rm nat}$$Niの厚いターゲットに入射した場合の核種生成断面積を、2台の$$gamma$$スペクトロメータを用いて測定した。これらのスペクトロメータは1332keVの$$gamma$$線に対してそれぞれ1.8と1.7keVの解像度を有する。実験の結果1112の生成核種が同定された。$$^{27}$$Al($$p$$,$$x$$)$$^{22}$$Na反応をモニター反応として利用した。実験データを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。

The cross sections for nuclide production in thin $$^{93}$$Nb and $$^{rm nat}$$Ni targets irradiated by 0.04 to 2.6 GeV protons are measured by direct $$gamma$$ spectrometry using two $$gamma$$ spectrometers with the resolutions of 1.8 and 1.7 keV for the $$^{60}$$Co 1332-keV $$gamma$$ line. As a result, 1112 yields of radioactive residual product nuclei have been obtained. The $$^{27}$$Al($$p$$, $$x$$)$$^{22}$$Na reaction has been used as a monitor reaction. The experimental data are compared with the MCNPX (BERTINI, ISABEL), CEM03.02, INCL4.2, INCL4.5, PHITS, and CASCADE07 calculations.
