| Abstract;A value of 3.7.+-.0.4Myr for the half-life of 53Mn, which is mainly produced by cosmic rays in meteorites, was reported by Honda et al. in 1971. Recent development of mass spectrometry and low energy photon spectrometry have enabled us to measure isotopic ratio and X-ray counting precisely and accurately than before. So we aim to redetermine the half-life of 53Mn by using modern mass spectrometer and low energy photon spectrometer. (author abst.) |
