Method for determining photonuclear reaction cross section and transforming atomic nucleus |
摘要 |
A germanium detector measures an energy spectrum of a gamma ray flux. The detector includes a cooling layer continuous over a periphery of the columnar germanium crystal. The cooling layer reduces current leakage induced by heat, so that high energy gamma rays can be precisely detected. A combination of a plurality of germanium crystal bodies connected one another to form the germanium crystal of at least 20 cm leads to a more precise detection of high energy gamma rays. A method for determining a photonuclear reaction cross section using the germanium detector enables measurement of the energy dependence of a photonuclear reaction cross section at high resolution. The method employs a white gamma ray flux radiated to a nuclide. The germanium detector measures the spectrum of a transmission gamma ray flux transmitted through the nuclide. Peaks are specified in the obtained spectrum. An atomic nucleus can be transformed using a monochromatic gamma ray flux having an energy level corresponding to the peak.
