An accurate solution for the three-nucleon bound state is obtained within 1 keV in the binding energy and, on the whole, better than 1% in the wave function, using a new systematic and efficient method. The method is based on a recently developed sep

The formalism for capture of linearly or circularly polarized γ rays on polarized targets with subsequent particle emission is presented in a convenient form. This allows one to generate the expressions for cross sections and analyzing powers in ter

The formalism for a linearly polarized γ-ray capture particle-out reaction is presented. The form given allows one to generate the expressions for the cross section as a function of the detected particle angle, θ, and the photon-polarization angle,

The numerical quality of the3H wave function obtained by the separable expansion method of Ernst, Shakin, and Thaler is examined. Separable approximations to the Paris potential with increasing accuracy are used in the1S0 and3S1-3D1 partial waves to

It is demonstrated that a clear convergent series for the three‐body observables is obtained with a new separable expansion method where several techniques are unified. In the method, we utilize both the separable expansions of EST and of Adhikari
