MODELLING THE YIELDS OF RARE EARTH ELEMENT ACTIVATION PRODUCTS FORMED VIA THE (γ,n)-REACTION CHANNEL ON THE M-30 MICROTRON

To implement the process of non-destructive photon-activation analysis of the content of rare earth elements in the samples under study using electron accelerators and to predict the results, reliable information on the yields of the products (radioisotopes) formed during their activation by generated bremsstrahlung photons is necessary. The results of modelling the yields of radioisotopes 44Sc, 88Y, 138La, 141Ce, 140Pr, 147,149Nd, 153Sm, 152Eu, 159Gd, 158Tb, 157Dy, 164Ho, 169Er, 168Tm, 169,175Yb, 174Lu, formed via the (γ,n)-reaction channel, are presented. Calculations were performed for the case of irradiating rare earth element samples at the electron accelerator of the Institute of Electron Physics of the National Academy of Sciences of Ukraine - the M-30 microtron, operating with bremsstrahlung photons at 12 MeV, taking into account its technical characteristics.
