Determination of Gross Sections for the Production of ⁷Be, ¹⁰Be and ²²Na by High-Energy Protons

7 Be Emission Cross Sections in High Energy Proton Induced Reactions on 51V, 93Nb and 197Au

“…A comparison of our radiochemically measured (p, 7 Be) cross sections with the data obtained without chemical separations [9] showed good agreement (within 10%) in case of V. However, for Nb our values are between 25 and 60% higher. For Au no other (p, 7 Be) cross section value has been reported.…”

“…The present communication describes our limited radiochemical studies on 7 Be emission in high energy proton induced reactions. These measurements were done parallel to those of Dittrich et al [9] in order to study the necessity of radiochemical separations and their effect on the accuracy of results, especially for those elements where a large number of radioactive products are expected.…”

The targets in the same group show similar characteristics in the evaluation of the cross sections.…”
