【 摘 要 】

Cross sections of alpha-particle induced reactions were determined on antimony targets using alpha-particle irradiation with a primary energy of 50 MeV. The standard stacked target technique, activation method and offline gamma-ray spectrometry were applied for determination of the reaction cross sections. Thin Sb targets prepared by vacuum evaporation onto Kapton backings were activated. Ti foils were inserted into the stack for monitoring the alpha-particle beam parameters and energy loss of the particles in the target by using the Ti-nat(alpha, x)51Cr monitor reaction. Reaction cross sections for formation of I-121,I-123,I-124,I-125,I-126, Te-121m,Te-g,Te-123m,Te-125m and Sb-118m,Sb-120m,Sb-122g were determined and compared to the available literature data and theoretical estimation of the cross sections from the TENDL-2019 data library.
