摘要: Abstract A calculation of the positive parity states for = 15 has been performed in a weak coupling approach. Based on particles sd shell and holes p-shell final eigenstates are found to be admixtures 1p−2h T h 0, 1 3p−4h configurations. Good agreement is obtained with experimental energy levels below 10 MeV. In O an additional 5 2 + state predicted at 8–9 MeV excitation energy. The wave functions compared structure informations from direct reactions. electromagnetic decay properties investigated most cases we find good experiment.
