Abstract. Mid-heavy nuclei with A ∼ 140–180 offer unique opportunities to study the collective and single-particle aspects of nuclear structure. This mass regime is a dynamic area where protons and neutrons generally occupy different orbitals, giving rise to complex structures with a wide variety of shapes, shape evolution and shape coexistence. To that end, measurements of nuclear lifetimes and transition matrix elements can be invaluable. Recent experimental activities of the NuSTRAP group in Athens have focused on γ-spectroscopy studies employing the ROSPHERE array in Magurele, Romania. A brief overview is reported.
