Outline of Final Research Achievements

We have developed a series of studies using correlated Gaussians in order to describe many-particle correlated motion like nuclear clustering. With this method we have published a number of papers including nuclear astrophysical research. Especially we have developed a computer code based on a framework of a core nucleus plus a few valence nucleons. This is important to reliably calculate the rate of 12C+α radiative capture reactions to produce 16O. However, the elimination of Pauli-forbidden configurations costs expensive configuration space. We think further development in theory and computer resources is needed to select important basis functions.
