TL;DR: In this paper, a simple, unified recipe to obtain precise solutions to virtually any few-body bound-state problem is given and applied to various problems in atomic, molecular, nuclear, subnuclear and solid state physics.

TL;DR: In this article, the trial wave functions are chosen to be combinations of correlated Gaussians, which are constructed from products of the singleparticle Gaussian wave packets through an integral transformation, thereby facilitating fully analytical calculations of the matrix elements.

TL;DR: The variational method complemented with the use of explicitly correlated Gaussian basis functions is one of the most powerful approaches currently used for calculating the properties of few-body systems as mentioned in this paper.

TL;DR: In this paper, a review of recent developments in the dynamical microscopic theories of cluster decay is reviewed with special emphasis on the nuclear structure aspects and physical interpretation of the models, concluding that the most essential prerequisite for a realistic model of the mother nucleus is that it should correctly describe the cluster correlation in the surface region.

TL;DR: In this article, the energy eigenvalue results and some wave function properties using the realistic four-nucleon interaction were compared, showing the high accuracy of their present ability to calculate the four-Nucleon bound state.
