Abstract: | Lunar soil samples of the Luna 16 Luna 20 missions were analysed by neutron activation in a neutron generator and a nuclear reactor, respectively, and following gammaspectrometry by NaI(T1) and Ge(Li) detectors. By 14 MeV neutron activation there were determined the abundances of 5 major elements (O, Mg, Al, Si, Fe) and by reactor activation the abundances of 18 major and trace elements (Na, K, Sc, Cr, Mn, Fe, Co, Mo, La, Ce, Sm, Eu, Tb, Yb, Lu, Hf, W, Th) and the detection limits of 4 additional elements (As, Rb, Sb, Cs). The standard rocks BM and GM of the ZGI were used as standards in the reactor activation analysis. |
