Activation cross sections of the natYb(p,xn)169Lu reaction for indirect production of the therapeutic radionuclide 169Yb

Activation cross sections of proton induced nuclear reactions on ytterbium up to 70MeV

“…This unusual large difference between the measured and calculated results may be explained by inadequate modelling of the (p,pxn) cross section. We observed similar underestimation in case of the nat Yb(p,pxn) 169 Yb reaction [1]. Results for the nat Yb(p,pn) 175 Yb reaction calculated by means of the EMPIRE code and taken from the TENDL-2008 database are plotted in addition to the ALICE-IPPE curve.…”

“…Production of 169 Yb through 169 Lu generator is a promising route at medium energy cyclotrons as it was discussed in our previous paper [1]. Here we are dealing with 167 Tm in detail.…”

“…The gamma spectra were evaluated in two ways: (1) with an automatic computer program using preset parameters and (2) with an interactive computer code using individual manual settings of the control parameters. The determination of the cross sections was iterative.…”

“…Publication of the results on production of 169 Yb and 169 Lu (as parent isotope), in detailed comparison with other production routes, is in progress [1].…”

Investigation of (d,x) nuclear reactions on natural ytterbium up to 24MeV

“…It can be alloyed with stainless steel to improve some of its mechanical properties [1], used as a doping agent in fibre optic cables [2], in making lasers [3], in ceramic industry [4], in dentistry [5], and used for the production of medically and technologically important radionuclides [6][7][8][9][10]. Therefore, an accurate knowledge of activation cross-sections of ytterbium isotopes is indispensable for various practical applications in science and technology.…”
