Sadler (Abilene Christian University); Crystal Ball Collaboration: ACU, ANL, ASU, BNL, GWU, KSU, PNPI, RBI, UCLA, UCol, UKa, UReg, ValUAbstract: A new Baryon Spectroscopy program has been initiated at the Brookhaven AGS facility with the Crystal Ball Spectrometer. This spectrometer, which consists of 672 NaI(Tl) crystals covering most of a 4-pi geometry, was originally built for studies of the excited charmonium spectrum at SLAC, and also used later at DESY. The excellent photon detection capabilities of this detector will allow the measurement of the coupling to neutral states not measured before in the field of Baryon Spectroscopy. |
