MEASUREMENT OF THE LONGITUDINAL ANALYZING POWER FOR NONCOPLANAR P-D BREAKUP

First measurements of the longitudinal analyzing power A(z) for noncop lanar p-d breakup at E(p) = 9 MeV in four kinematically complete confi gurations are presented. The measurements are compared with Faddeev ca lculations obtained with the Bonn B nucleon-nucleon interaction and th e 2 pi-exchange Tucson-Melbourne three-nucleon force. The measured ana lyzing powers and the corresponding theoretical predictions are very s mall in magnitude and compatible within the error bars of the data. Be cause of the smallness of A(z), the expected enhanced sensitivity to t hree-nucleon force effects is not seen in this: low energy region.
