摘要

【正】 The cross sections for the formation of long-lived products ¹⁰⁸Ag^m（6⁺,433a）,¹⁵⁰Eu^m（5^-,36.9a）,¹⁵⁸Tb（3^-,180a）and ¹⁷⁸Hf^m2（16⁺,31a）are measured in the（n,2n）reaction on the elementsof ¹⁰⁹Ag,¹⁵¹Eu,¹⁵⁹Tb and ⁷⁹Hf at neutron energies of 9.5 MeV and 0.9 MeV,respectively.The neu-tron fluence is obtained through the ¹⁹⁷Au（n,2n）¹⁹⁶Au reaction.The D（d,n）³He reaction is used as neu-tron source at the tandem accelerator.The present results are compared with the averaged values of theo-retical cross sections and the experimental data.
