Production Gross Sections of ^109gIn,^111gIn,^113mIn and ^115gCd Formed by Deuterons on Cadmium

Activation cross sections on cadmium: Deuteron induced nuclear reactions up to 40MeV

“…We could measure the cumulative ground state formation only after the complete IT decay of the metastable state (half life: 1.34 min). Our cross section values agree well with those of Usher et al [13] as shown in Fig. 4, but the theoretical curve (ALICE-IPPE) lies higher than our measured points.…”

“…13a and 13b) and does not decay into the ground state as both states decay by b À emission. Results of Usher et al [13] agree well below and differ significantly above 13 MeV from our data measured for 115g Cd. Natowitz and Wolke [19] and Tárkányi et al [3] measured cross sections on 114 Cd target.…”

“…8. Data of Usher et al [13] differ by an order of magnitude from our experimental results and none of them are close to the ALICE-IPPE curve which includes the ground state as well.…”

“…Cumulative cross sections were measured after the complete decay of the metastable 111m In (half life: 7.7 min). The shape of our and Usher's [13] measured excitation functions are similar to that calculated by ALICE-IPPE, but do not agree with each other in absolute values (see Fig. 6).…”

“…Usher et al [12,13] and Nassiff et al [14] presented not sigmas but r p P n i a i =A where r p ; A and P i a i are production cross section, average atomic weight and isotopic abundance, respectively. To obtain cross sections measured on natural cadmium we multiplied the presented values by A and plotted them in the proper figures.…”
