Abstract

We update our Letter-of-Intent 202 for Measurement of Spin Observables in the ~p ~d Breakup Reaction. An estimate of the overall beam time needed for completing the measurements is specied and a timeline in view of the planned PAX experiments is presented. The proposal aims at a study of the three nucleon continuum in proton deuteron breakup reactions, between 30 and 50 MeV proton beam energies, an energy range where there have been few and limited measurements. The large coverage of the PAX detection setup and the energy range chosen will provide essential new data intended as a laboratory for chiral eective eld theory, the modern theory for nuclear forces relevant at low and intermediate energies. Vector and tensor analyzing powers and spin correlation coecients will be measured and evaluated over large kinematical areas in the ve parameter phase space of the nal state containing three nucleons. For the analysis the sampling method will be used, a technique developed specically for the complex analysis of three particle nal states, providing a direct comparison between experiment and theory.
