The heavy ion irradiation is used for the first time to simulate the radiation damage produced by reactor neutrons in home-made modified stainless steels. The produced radiation damage is investigated by the positron annihilation spectroscopy. No detectable radiation damage is observed in the home-made modified stainless steels irradiated by 81.6 MeV carbon ions to a total dose of 3.3×1016 cm-2 , indicating that the home-made modified stainless steel of this type has good radiation resistant properties. 相似文献

A BaF2 time differential perturbed angular distribution spectrometer has been established at the HI-13 tandem accelerator in CIAE.The time resolution of the spectrometer is 195ps and the nonlinearity is less than 2%.The spectrometer works very stably and no time drift is found over a period of experimental runs.This spectrometer has been successfully used in the g-factor measurement of 43Sc(19/2^-,3.1232MeV). 相似文献
