Results from the Spin Program at COSY-ANKE

It was once claimed that in strong interaction physics “Spin is an inessential complication” [1]. This rather negative attitude ignores certain practical applications and surely dismisses the beauty inherent in many phenomena involving particle polarization. Recognizing this, a program was outlined several years ago to exploit the possibilities of carrying out experiments with polarized beams and targets at ANKE [2]. This facility is based around a magnetic spectrometer sited at an internal target station of the COoler SYnchrotron and storage ring COSY of the Forschungszentrum Julich. The basic features of the complex were described in a previous issue [3] and we shall here concentrate on a few of the fruits of the spin program.
