About thirty nuclei in the A ∼ 100 mass region have been produced as fission fragments in the reaction 36S+162Dy at 162 MeV bombarding energy. They have been individually identified from their γ-ray transitions detected using an early implementation of EUROGAM array. The mass region reached develops from Z = 34 (Se) to Z -48 (Cd) and from N = 46 to N = 66, along the valley at stability and beyond it towards neutron-rich side. Level schemes of already known stable or neutronrich nuclei have been extended to higher spins. From cross coincidences between transitions in complementary fragments, γ-rays de-exciting highspin states of new isotopes have been identified and some aspects of the fission mechanism have been analyzed.
