Nuclear Physics: Estimating the Mean Lifetime from Partially Observed Events
Author(s): Jan Saren*
In nuclear physics, one important property of particles to identify is their mean lifetime. The arrivals and subsequent radioactive decays (departures)
of single radioactive nuclei can be detected by cutting-edge particle detectors. When there is inconsistency between arrivals and departures and
only partial observation of departures, problems arise. Experiments in which the arrival rate is set very low to allow for matching of arrivals and
departures are inefficient. An estimation technique that works for a wide range of arrival rates is what we propose. An initial estimator and a
method for correcting numerical bias are combined in this approach. The method provides accurate estimates regardless of the arrival rate, as
demonstrated by examples and simulations based on data on Lutetium isotope 155 alpha decays. The estimation technique makes it possible
