Steigerwald results reported in SPIN 2000 JLab measurements in June 2012

Steigerwald results reported in SPIN 2000 JLab measurements in June 2012

Steigerwald results reported in SPIN 2000 JLab measurements in June 2012 after 12 years good agreement Results depend on (energy=same, targets=same, TOF cut=same) Do we agree at a precision level? similar at few percent, but what about <1% ??? => motivates experiment.
