Testing ab initio nuclear structure in neutron-rich nuclei: Lifetime measurements of second 2⁺ state in ¹⁶C and ²⁰O

NUCLEAR REACTIONS ¹⁸¹Ta(¹⁸O, X)¹⁶C/¹⁹O/²⁰O, E=7.0 MeV/nucleon; measured reaction products, Eγ, Iγ, (particle)γ-coin, level half-lives by Doppler-shift attenuation method and Monte Carlo simulations using AGATA array, coupled to the PARIS scintillator array and to the VAMOS++ magnetic spectrometer at GANIL. ¹⁶C, ^19,20O; deduced levels, J, π. Comparison with predictions of the valence-space in-medium similarity renormalization group (VS-IMSRG) and the no-core shell model (NCSM) with NN and 3N interactions.
