Light nuclei in the p-shell are studied in the Fermionic Molecular Dynamics model. No a priori assumptions are made with respect to cluster structure or single-particle energies. The same effective interaction based on the Argonne V18 interaction is used for all nuclei. Short-range central and tensor correlations are treated explicitly using a unitary correlation operator. Calculations of binding energies and radii for Helium and Carbon isotopes are presented. The evolution of cluster and single-particle structures with increasing neutron number are discussed. The spectrum of 12C is calculated in a multiconfiguration calculation. The molecular structure of the excited states is investigated. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]
