摘要: Abstract The half-life of thallium-204 was determined to have a value 3·7731±0·0013 yr (probable error). This obtained from calorimetric measurements the decay in power output sample irradiated natural thallium over an 8-yr period. average neutron flux on during irradiation by use adjacent bismuth coupons. A 2·173 MeV-barn for product nuclear cross-section (σ) and particulate energy. Using accepted thallium-203 11 barn slow neutrons, energy β particles becomes 0·1975 MeV.
