【 摘 要 】

In the frame of a systematic study of the activation cross-sections of the deuteron induced nuclear reactions, excitation functions of the Yb-nat(d,xn)Lu-177,Lu-173,Lu-172mg,Lu-171mg,Lu-170,Lu-169, Yb-nat(d,x)Yb-175,Yb-169 and Yb-nat(d,x)Tm-173,Tm-172,Tm-168,Tm-167,Tm-165 reactions are studied up to 40 MeV, a few of them for the first time. Cross-sections were measured with the activation method using a stacked foil irradiation technique and high resolution gamma-ray spectrometry. The experimental data are analyzed and compared to the results of the theoretical model codes ALICE-IPPE, EMPIRE-II and TALYS. From the measured cross-section data integral production yields were calculated. Applications of the new cross-sections are discussed. (C) 2013 Elsevier B.V. All rights reserved.
