Abstract

The computational scheme and calculation results of metastable and scattering states for Beryllium dimer important for laser spectroscopy are presented. The mathematical model is formulated as a multidimensional boundary-value problem with mixed-type boundary conditions, which is reduced in the adiabatic representation to a second-order ordinary differential equation. The solution to the problem is performed using the author's software package (the libraries of programs of the journal Computer Physics Communications and JINRLIB) that implement the high-accuracy finite element method.
