The Continuum

We present analyses of breakup effects of 6 He on the elastic scattering by the continuum-discretized coupled-channels method, in which the reaction system is described as a four-body model, n+n+4 He +target. In this analysis, three-body breakup continuum of 6 He is discretized by daiagonalizing the internal Hamiltonian of 6 He in a space spanned by the Gaussian basis functions. The calculated elastic cross sections are in good agreement with the experimental data, which shows that nuclear and Coulomb breakup effects are significant.

The Continuum

A quantum mechanical theory for the ℏω+AB→A+B++e- three body breakup is presented. The theory is based on the Continuum Coupled Channels expansion (CCC) in which the three body wave-function is expanded in terms of square integrable and (flux carrying) continuum states. The theory consistently treats the accompanying processes of three body inelastic collisions, dissociative attachment and Penning ionization. Applications to the dissociative photoionization of H2 and HD are presented. The relevant equations are solved exactly using the Artificial Channel method. Excellent agreement is obtained with experiment, concerning the proton kinetic energy distribution.
