pd fusion with polarized deuterons

A model-independent irreducible tensor formalism that was developed earlier to analyze measurements of p-vectorp-vector{yields}pp{pi} deg. is extended to present a theoretical discussion of p-vectorp-vector{yields}pp{omega} and of {omega} polarization in pp{yields}pp{omega}-vector and in pp-vector{yields}pp{omega}-vector. The recent measurement of an unpolarized differential cross section for pp{yields}pp{omega} is analyzed by use of this theoretical formalism.

TENSOR FORCE AND NN SCATTERING WITH POLARIZED BEAM AND TARGET

We present here a model-independent irreducible tensor approach to meson production in NN collisions, which leads to a spin-structure of the T-matrix valid at all energies together with exact partial-wave expansions for the reaction amplitudes. We then make use of these expressions to estimate the values of the partial-wave amplitudes for the reaction

Irreducible tensor phenomenology for pdto3Hepi+pi-

A model-independent irreducible tensor formalism is developed to discuss photon polarization in np fusion. It is shown that photon polarization arising out of the interference of the dominant isovector M1 amplitude at thermal neutron energies with the small isoscalar M1 and E2 amplitudes can be studied with advantage in suitably designed polarized beam and polarized target experiments, where the neutron and proton polarizations are either opposite to each other or orthogonal to each other.
