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 $\gamma\gamma$-coincidence relations and angular distribution ratios a significantly extended level scheme has been constructed up to $E_x\sim 7.8$ MeV and I=35/2. The experimental results were described within the framework of the shell model. Candidates for states fully aligned in the $\pi g_{9/2}^{-3}\nu (d_{5/2},g_{7/2})^2$ valence configuration space were found at 4109 and 6265 keV.
