Název v původním jazyce

Yield of radionuclides and isomers produced in the fragmentation of W-nat and W-186 (97

Popis výsledku v původním jazyce

Yields and cross-sections of the radioactive nuclides produced after the irradiation of natural composition W and enriched W-186 targets at the Dubna synchrocyclotron were measured using the gamma-ray spectroscopy methods with high-resolution Ge detectors. Among the detected nuclides we identified the spallation and fission products. High-spin isomeric states in the Hf and Lu nuclides were populated and the isomer-to-ground state ratios could be estimated. The nuclide yields were calculated using the LAHET code at six different values of the proton energy in the range from 100 to 800 MeV both for the W-nat and enriched 186W targets. The measured isotope yields are in general good agreement with the calculations. A shortcoming of the code is the inability to predict isomer-to-ground state ratios. The experimental data show that the Lu-177m, Hf-178m2 and Hf-179m2 high-spin isomers are produced with a 2.5 times higher yield in the 97% enriched W-186 target as compared to the W-nat targ...
