Název v původním jazyce

Trinucleon photo-reactions with Delta-isobar excitation: Radiative nucleon-deuteron capture and two-body photo-disintegration of the three-nucleon state.

Popis výsledku v původním jazyce

Radiative nucleon-deuteron capture and photo-disintegration of the three-nucleon bound state with two-body final states are described. The description uses nucleon degrees of freedom extended to include the excitation of a single nucleon to a Delta-isobar. The baryonic interaction and the electromagnetic current couple nucleonic states with a Delta-isobar. Exact solutions of three-particle scattering eqations are employed for the initial or final states of the reactions. The current has one-baryon and two-baryon contributions in all considered multipoles. The role of the Delta-isobar in the description of the considered photo-reactions is discused and found to be moderate. The spin observables A(yy) and T-20 at 90degrees lab scattering angle can be calculated model-independently from the E1 Siegert term in the long-wavelength limit.
