Measurement of the free neutron lifetime using the neutron spectrometer on NASA's Lunar Prospector mission

RADIOACTIVITY ¹n(β^-); measured E(n), I(n), T_1/2 of decay of free neutron using neutron spectrometer consisting of two cylindrical gas proportional counters of ³He on NASA's Lunar Prospector spacecraft during the elliptical orbits in 1998-99; feasibility of precise measurement of T_1/2 of free neutron from space, with an earlier measurement reported in 2020 using NASA's MESSENGER data. Comparison with recommended half-life by the Particle Data Group.
