Abstract

The yields of ⁷Be and ¹⁰Be produced by bremsstrahlung having a maximum energy (E₀) of 200 MeV in ^natCu, ^natAg and ¹⁹⁷Au targets were investigated by the AMS technique at MALT of the University of Tokyo. It was found that the yields at E₀=200 MeV were much lower than those at E₀≥250 MeV, obtained in our previous works. A change in the yields of the fragmentation component in the target-mass dependence was observed at E₀=200 MeV when compared with those at E₀≥250 MeV. However, the ratios of the fragmentation yield of ¹⁰Be to that of ⁷Be remained unchanged throughout the concerned E₀.
