Evolution of shape and collectivity along the Ge isotopic chain: The case of ⁸⁰Ge

NUCLEAR REACTIONS ¹⁹⁶Pt(⁸⁰Ge, ⁸⁰Ge'), E=3.52 MeV/nucleon [secondary ⁸⁰Ge beam produced in ⁹Be(⁸²Se, X) reaction]; measured reaction products Eγ, Iγ, (particle)γ-coin. ⁸⁰Ge; deduced B(E2), E2 and M1 matrix elements, spectroscopic quadrupole moments. GOSIA analisys. Comparison to other experimental results and shell model calculations. Results indicate a large prolate deformation in ⁸⁰Ge. Systematics of B(E2) and quadrupole moments for even-A Ge isotopes. Detector system - Joint Array for Nuclear Structure (JANUS) consisting of two annular silicon detectors (Bambino2) with the Segmented Germanium Array (SeGA). Beam provided by reaccelerator facility (ReA3) of NSCL.
