N2 - Significant computational resources are necessary to calculate bound and resonance states of weakly bound systems with high accuracy. The discrete-variable representation method allows to reduce the computational complexity of determining the matrix elements of operators in the frame of variational methods. In this work, the binding energies of the Li-He(formula presented) and He(formula presented) systems are calculated and compared with other results.
