Query: The Modified J-Matrix Approach for Cluster Descriptions of Light Nuclei   We present a fully microscopic three-cluster nuclear model for light nuclei
on the basis of a J-Matrix approach. We apply the Modified J-Matrix method on
$^{6}He$ and $^{6}Be$ for both scattering and reaction problems, analyse the
Modified J-Matrix calculation, and compare the results to experimental data.
