Abstract
Excited states of ⁹⁹Ag were populated via the ⁵⁰Cr + ⁵⁸Ni (261 MeV) reaction using the NORDBALL detector array equipped with charged-particle and neutron detector systems for reaction channel separation. On the basis of the measured -coincidence relations and angular distribution ratios a significantly extended level scheme has been constructed up to  MeV and I=35/2. The experimental results were described within the framework of the shell model. Candidates for states fully aligned in the valence configuration space were found at 4109 and 6265 keV.
