Half-lives of 132La and 135La
The half-lives of 135La and 132La were determined via serial gamma spectroscopy, and the half-life of 135La was further determined by a high-precision ionization-chambermeasurement. The results are 18.91(2) hr for 135La and 4.59(4) hr for 132La compared with the previously compiled values of 19.5(2) hr and 4.8(2) hr, respectively.
These lanthanum isotopes comprise a medically interesting system with positron emitter 132La and Auger-electron emitter 135La forming a theranostic 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.
