Recoil protons from the β-decay of unpolarized neutrons are stored in a cryogenic ion trap formed by the superposition of an axisymmetric electrostatic field on a coaxial magnetic field, which varies uniformly in space between regions of high (~4.30

Autor: A. P. Williams, J. Byrne, S. J. Smidt, C. G. Habeck, P.G. Dawber, J. A. Spain

Publikováno v: Europhysics Letters (EPL). 33:187-192

We have re-evaluated the results of the neutron lifetime experiment based on storage of decay protons in a Penning trap. Combining improved statistical treatment of the data with precise measurements of the magnetic-field distribution in the trap, we
