Abstract
Shell-model calculations taking into account all 1ħω configurations have been performed for the A = 14,13 systems. The spurious states due to the c.m. motion have been removed exactly. The level schemes, complete sets of single-particle spectroscopic amplitudes and electromagnetic transition rates have been calculated. These quantities are compared with the available data and the results of other calculations. A good description of the non-normal parity states below 10 MeV is obtained throughout, the deviations of the excitation energies (17 levels) are less than 0.7 MeV. Most of the states in this energy region have a simple parent structure and their main properties can be explained also in a more restricted configuration space. For the higher-lying levels the model provides the first results which are consistent with the reported experiments.
