# Linear relations between high-purity energy levels in A=12-16 nuclei

Article

We have assumed the T=0 negative-parity quartets of levels in A=14 nuclei, as well as the T=1 negative-parity quartet in A=16 nuclei, to represent pure configurations. Linear relationships between the energies of these groups of levels produce results which are consistent with the relevant part of the single-particle energy spectrum in this region. From the given A=14 energy values conclusions are made concerning the low positive-parity levels in A=15. Due consideration is given to the necessary Coulomb corrections in all the calculations.
