The neutron-deficient semimagic (neutron number N=50) Rh95 nucleus has been produced at high spins using the projectile-target system Ca40+Ni58 at 125 MeV beam energy. The γ-decays of levels populated by the 3p fusion evaporation reaction channel were studied using γ-γ coincidences, and 20 new γ-ray transitions involving 15 new positive- and negative-parity states were observed. Spin and parity for many of the excited states were firmly deduced for the first time using the combined directional angular correlation and direction-polarization techniques. The observed structures are discussed within the framework of large-scale shell model calculations. E1 transition strengths were deduced and used together with the results of the shell model calculations to study the contribution of different particle-hole configurations, in particular for analyzing contributions from core-excited configurations.
