Experimental measurements and nuclear model calculations on the excitation functions of natCe(3He,xn)and 141Pr(p,xn) reactions with special reference to production of the therapeutic radionuclide 140Nd
For production of the therapy related Auger electron emitting, neutron deficient nuclide Nd-140 (T-1/2 = 3.37 d) two routes were investigated: the nuclear reaction Ce-nat(He-3. xn)Nd-140 over the energy range from 15 to 36 MeV and the reaction Pr-141(p, 2n)Nd-140 from 10 to 45 MeV. Some competing re...

For production of the therapy related Auger electron emitting, neutron deficient nuclide Nd-140 (T-1/2 = 3.37 d) two routes were investigated: the nuclear reaction Ce-nat(He-3. xn)Nd-140 over the energy range from 15 to 36 MeV and the reaction Pr-141(p, 2n)Nd-140 from 10 to 45 MeV. Some competing reactions leading to other Nd isotopes, namely Nd-139 and Nd-141, as well as to Ce-139 were also investigated. Thin samples of cerium(IV)-oxide and praseodymium(III)oxide were obtained by sedimentation and the conventional stacked-foil technique was used for cross section measurements. All the experimental data obtained in this work were compared with the results of theoretical calculations using the exciton model code ALICE-IPPE as well as with literature experimental data, if available. In general, good agreement between experimental and theoretical results was found. The theoretical thick target yields of all the product nuclides were calculated from the measured excitation functions. The theoretical thick target yield of Nd-140 over the energy range E-3He = 35 -> 20 MeV amounts to 12 MBq/mu A(.)h and over the energy range E-p = 30 -> 15 MeV to 210MBq/mu A.h. A comparison of the two Nd-140-producing reactions is presented. |
