Abstract
The half-lives of La and La were determined via gamma spectroscopy and high-precision ionization chamber measurements. The results are 18.930(6) h for La and 4.59(4) h for La compared to the previously compiled values of 19.5(2) h and 4.8(2) h, respectively. The new results represent an improvement in the precision and accuracy of both values. These lanthanum isotopes comprise a medically interesting system with positron emitter La and Auger electron emitter La forming a matched pair for internal diagnostics and therapeutics. The precise half-lives are necessary for proper evaluation of their value in medicine and for a more representative tabulation of nuclear data.
