Generalized collisional radiative model for light elements. Part B: Data for the Be isonuclear sequence

Abstract A first-stage collision database is assembled which contains electron-impact excitation, ionization, and recombination rate coefficients for Be, Be + , Be 2+ , and Be 3+ . The first-stage database is constructed using the R -matrix with pseudo-states, time-dependent close-coupling, and perturbative, distorted-wave methods. A second-stage collision database is then assembled which contains generalized collisional-radiative and radiated power loss coefficients. The second-stage database is constructed by solution of collisional-radiative equations in the quasi-static equilibrium approximation using the first-stage database. Both collision database stages reside in electronic form at the ORNL Controlled Fusion Atomic Data Center and in the ADAS database, and are easily accessed over the worldwide internet.
