Abstract

Among measurements of the neutron lifetime, there is a 1% difference between proton-counting methods and neutron-counting methods. In this paper, a new electron-counting method with a magnetic field aiming for a 0.1% accuracy is proposed, which would have a possibility to probe the discrepancy.
