Abstract

Samples of ⁸⁸Rb were produced by the irradiation of U₃O₈. A series of procedures were applied to extract pure radioactive solution of ⁸⁸Rb. Experimental data was recorded by a 4πβγ-coincidence measurement system. Two rounds of experiments were performed to obtain four sets of measurement data. The measured half-life of ⁸⁸Rb obtained from the average of the 4πβ and 4πβγ-coincidence methods was 17.78 ± 0.05 min, in good agreement with previously reported values but with a significantly reduced uncertainty.
