Title: Neutron β Decay: Status and Future of the Asymmetry Measurement

Abstract

With more intense sources of cold and ultracold neutrons becoming available and with improved experimental techniques being developed, determination of Ι Vud l from neutron β decay with a similar precision to that from from superallowed β decays is within reach. Determination of I Vud l from neutron β decay, free from nuclear corrections, holds the most promise for a further improvement of the determination of I Vud l· The current and future neutron β decay correlation experiments including the UCNA experiment at Los Alamos National Laboratory are reviewed.
