摘要
We have determined the isomeric ratios in Te-120(gamma, n)Te-119m,Te-g, Te-122(gamma, n)Te-121m,Te-g, Te-128(gamma, n)Te-127m,Te-g and Te-130(gamma, n)Te-129m,Te-g photonuclear reactions of natural tellurium induced by bremsstrahlungs with end-point energies in the giant dipole resonance (GDR) region. The investigated samples were irradiated at electron accelerator Microtron MT-25 of the Flerov Laboratory of Nuclear Reaction, Joint Institute for Nuclear Research, Dubna, Russia. The gamma spectra of the samples irradiated were measured with spectroscopic system consisting of 8192 channel analyzer and high-energy resolution (180 keV at gamma ray 1,332 keV of Co-60) HP(Ge) semiconductor detector Canberra. The GENIE2000 (Canberra) computer program was used for data processing. The results were discussed and compared with those of other authors.
