Clustering in Nuclei

Nuclear clustering, alpha decays, and multiparticle correlations are important components of nuclear dynamics. In our work we use the configuration interaction technique combined with the resonating group method based on a harmonic oscillator basis to treat the reaction and multiclustering dynamics in atomic nuclei. Our approach is translationally invariant and preserves the Pauli principle.  Details can be found in the following publicaitons

Following the link below you can find detailed tables containing alpha clustering spectroscopic factors for sd-shell nuclei (USDB shell model Hamiltonian). The tables contain following columns: parent state spin and parity, parent absolute energy from 16O core, parent state excitation energy, old spectroscopic factor eq. (17) and renormalized spectroscopic factors eq. (29) from this reference. The last two columns give running summs of old and new spectroscopic factors. All spectroscopic factors are given for decay into ground states of corresponding A-4 nuclear systems.
