Comparative yields of alkali elements and thallium from uranium irradiated with GeV protons, $^{3}$He and $^{12}$C

Mostrar otras versiones (1)

Mass-separated ion beams of the alkali elements Na, K and Fr, and of the element Tl, are produced by bombarding a uranium target with 600 MeV protons, 890 MeV /sup 3/He/sup 2+/, and 936 MeV /sup 12/C/sup 4+/. Isotopic production yields are reported. In the case of the /sup 12/C beam, these are thick...

Sumario:Mass-separated ion beams of the alkali elements Na, K and Fr, and of the element Tl, are produced by bombarding a uranium target with 600 MeV protons, 890 MeV /sup 3/He/sup 2+/, and 936 MeV /sup 12/C/sup 4+/. Isotopic production yields are reported. In the case of the /sup 12/C beam, these are thick target yields. Absolute cross-sections for the proton beam data are deduced by normalizing the delay-time corrected yield curves to measured cross-sections. For products farthest away from stability, the /sup 3/He/sup 2+/ beam generally gives the highest yields. (17 refs).
