keyword=Update of efficiency.
We recalculated the efficiency for the momentum of 0.666 GeV. Twoo improvements were made: the spectrometers were redirected and so we see less of the windows and a better cut on the shower counter was made for this momentum. The result is that the efficiency has changed from .18 to .48. We will use .40 for our calculations.
