Final State Interaction in Neutron Deuteron Charge Exchange Reaction at Small Transfer Momentum
نویسنده
چکیده
Analysis of the nd → p(nn) reaction in a Gev-energy region is performed in the framework based on the multiple-scattering theory for the few nucleon system. The special kinematic condition, when momentum transfer from neutron beam to final proton closes to zero, is considered. The possibility to extract the spin-flip term of the elementary np → pn amplitude from nd-breakup process is investigated. The energy dependence of the ratio R = dσnd dΩ / dΩ is obtained taking account of the final state interaction two outgoing neutrons in S0-state.

متن کاملThe neutron - proton charge - exchange amplitudes measured in the dp → ppn reaction
The unpolarised differential cross section and the two deuteron tensor analysing powers Axx and Ayy of the dp → {pp}sn charge-exchange reaction have been measured with the ANKE spectrometer at the COSY storage ring. Using deuteron beams with energies 1.2, 1.6, 1.8, and 2.27GeV, data were obtained for small momentum transfers to a {pp}s system with low excitation energy. The results at the three...
متن کاملApparent Coulomb reacceleration of neutrons in electrodissociation of the deuteron.
We demonstrate that the final state p-n interaction in the reaction of electrodissociation of the deuteron at large Q in a static external field leads to the apparent reacceleration of neutrons. The shift of the neutron velocity from the velocity of the deuteron beam is related to the quantum-mechanical forward-backward asymmetry of the missing momentum distribution in the H(e, ep)n scattering....
متن کاملTensor analyzing powers in forward angle exclusive π - meson photoproduction on deuteron
Tensor analyzing powers in forward angle exclusive π-meson photoproduction on deuteron. Abstract The target tensor analyzing powers of the process γd → π − pp had been studied in the plane wave impulse approximation, if both ejected protons are detected in coincidence and in the directions, symmetrical respect to the incoming photon momentum , being in the proton plane. The matrix elements of t...
متن کاملParity violation in quasifree electron scattering off the deuteron
For deuteron electroweak disintegration, parity violating effects are investigated which arise from the interference of γ and Z exchange as well as from the hadronic sector via a small parity violating component in the deuteron. The general formalism for the differential cross section and polarization observables of electromagnetic deuteron disintegration is extended to incorporate parity viola...
