Tóm tắt

In this paper, the computational scheme and calculation results of scattering functions for metastable states of a diatomic beryllium molecule in laser spectroscopy are presented. The solution to the problem is performed using the authors' software package with the high-accuracy finite element method. The procedure of matching tabulated potential functions with van der Waals asymptotic potential using Hermite interpolation polynomials which provides continuity of both the function itself and its derivative is presented. The efficiency of the proposed approach is demonstrated by the spectrum of rotational-vibrational metastable states with complex-valued energy eigenvalues in the diatomic beryllium molecule. For selected metastable states, the corresponding scattering states with real-values resonance energies are calculated and shown in graphs.
