Moller Measurements for 4He(e,e'p)3H polarization transfer, April-May 2000


Last updated: Thu, 13 Dec 2001 moller@jlab.org

Here a summary is given of the Moller measurements done for E93-049 Polarization Transfer in the Reaction 4He(e,e'p)3H in the Quasi-elastic Scattering Region running in Apr-May 2000.

The results enclosed have been corrected for the newer value of the target polarization (7.95%), dead time (1%), and the sign of helicity. The helicity sign belongs to the period when the "helicity signal" is in a state of logical 1.
