E2 rotational invariants of 0₁⁺ and 2₁⁺ states for ¹⁰⁶Cd: The emergence of collective rotation

NUCLEAR REACTIONS ²⁰⁸Pb(¹⁰⁶Cd, ¹⁰⁶Cd'), E=3.849 MeV/nucleon; measured Doppler-corrected γ-ray spectra, Eγ, Iγ, (¹⁰⁶Cd)γ-coin using GRETINA array with 32 HPGe crystals for γ detection, and CHICO array for particles at the ATLAS-ANL facility. ¹⁰⁶Cd; deduced levels, J, π, E2 and E3 matrix elements using GOSIA analysis code, E2 transition strengths, spectroscopic quadrupole moments, electric quadrupole invariants (Kumar-Cline sum rules) Q³cos(3δ), axial-symmetry parameter δ. Comparison with beyond mean-field (BMF) and shell-model calculations, and with previous experimental data.
