A broad range of physics phenomena can be addressed by high-resolution in-beam γ-ray spectroscopy experiments with radioactive beams offered within the RISING project. In the "Fast Beam Campaign" secondary beams selected at relativistic energies by the FRS were used for Coulomb excitation or secondary fragmentation experiments to study projectile like nuclei by measuring de-excitation photons. Alternatively, the relativistic radioactive beams, both in their ground and isomeric states, were implanted and their decay could be investigated. Highlights of the on-going "Stopped Beam Campaign" include a study of mirror symmetry based on the ⁵⁴Ni–⁵⁴Fe pair with isomeric proton radioactivity, T=0 and T=1 isospin competing states studied in heavy N=Z nuclei ⁸²Nb and ⁸⁶Tc, ¹³²Sn region with isomers discovered in the neutron rich r-process waiting point nucleus ¹³⁰Cd and ¹³¹In, and structure of ²⁰⁴Pt, 4 protons below ²⁰⁸Pb. The experience gained in the RISING project will flow into the HISPEC/DESPEC projects for the future FAIR facility.
