  In the frame of a systematic study of the activation cross-sections of the
deuteron induced nuclear reactions, excitation functions of the
natYb(d,xn)177,173,172mg,171mg,170,169Lu, natYb(d,x)175,169Yb and
natYb(d,x)173,172,168,167,165Tm 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.
