The structure of the A/Z = 3 nucleus B-15 has been investigated using the in-beam gamma-spectroscopy technique with a fragmentation reaction of a S-36 beam on a Be-9 target at 77.5 MeV . A. The fragments were identified and selected by their energy loss and time of flight using the SPEG spectrograph. gamma-ray energies and intensities have been measured in coincidence with the projectile- like fragments. From this information as well as from the gammagamma-coincidence relationships a level scheme is proposed for B-15 up to the neutron separation energy. The experimental results have been interpreted using shell model calculation sin the psd valence space. Effects of the weakly bound nature of the valence neutrons have been observed

Struktura jádra s A/Z=3 byla zkoumána pomocí techniky gamma spektroskopie ve svazku. Experimentální výsledky byly interpretovány v rámci slupkového modelu v psd valenčního prostoru.
