|Abstract:||The half-lives of 214Po and 218Rn have been measured. The radionuclides were produced in the decay of a 230U source and the emitted alpha-particles were measured in nearly-2 pi geometry with an ion-implanted planar silicon detector. The data acquisition was performed with a digitizer operated in list mode, saving the energy and time of detection (10 ns precision timestamp) of each event. The half-lives were deduced from the time differences between the alpha-decays populating the nucleus of interest and those corresponding to its decay. Different methods were applied, based on delayed coincidence counting and time interval distribution analysis. The resulting half-lives are 33.75 (15) ms for 218Rn and 164.2 (6) µs for 214Po, both in agreement with some of the literature values, and obtained with higher precision in this work.|
