Abstract: Isotope ratios of mollusk shell carbonates are commonly used to reconstruct past environmental conditions, but the shell organic matrix is often overlooked. Here, the authors find the hydrogen and oxygen isotope compositions of the organic… read more here.

Abstract: We study the performance of self-consistent mean-field and beyond-mean-field approximations in shell-model valence spaces. In particular, Hartree-Fock-Bogolyubov, particle-number variation after projection and projected generator coordinate methods are applied to obtain ground-state and excitation energies for… read more here.
