本文提出了一种利用Mo-100（n，2n）Mo-99反应制备核医学用Mo-99的新方法。已知反应截面在中子能量E范围为12至17 MeV时类似于1.5 B：比Mo-98的热中子俘获截面大10倍。通过用类似于10（13）n/（cm（2）s）的中子在类似于14 MeV的E-n下照射浓缩Mo-100靶198 h，一次呼叫产生79 GBq/g Mo-99比活度。由于Mo-100（n，p）Nb-100、Mo-100（n，np）Nb-99和Mo-100（n，alpha）Zr-97在12
We have proposed a new route to produce Mo-99 for nuclear medicine by the Mo-100(n, 2n)Mo-99 reaction. The reaction cross section is known to be similar to 1.5 b in the neutron energy, E, range from 12 to 17 MeV: 10-times larger than the thermal-neutron capture cross section of Mo-98. By irradiating an enriched Mo-100 target for 198 h with neutrons of similar to 10(13) n/(cm(2) s) at E-n similar to 14 MeV, one call produce 79 GBq/g specific activity of Mo-99. Since the cross sections for Mo-100(n, p)Nb-100, Mo-100(n, np)Nb-99 and Mo-100(n, alpha)Zr-97 at 12
