WebExperimental determination of the cross sections of proton capture on radioactive nuclei is extremely difficult. Therefore, it is of substantial interest for the understanding of the production of the p-nuclei. For the first time, a direct measurement of proton-capture cross sections on stored, radioactive ions became possible in an energy range of interest for … WebPlace the cylinder back on top of the cross. Using a 50 cm 3 measuring cylinder, measure 50 cm 3 of iron (III) nitrate solution. Pour the iron (III) nitrate solution into the sodium thiosulfate solution, and start the timer. An immediate dark violet solution is observed which turns colourless after a few minutes.
