Cross-shell excited configurations in the structure of ³⁴Si

RADIOACTIVITY ^34,34mAl(β^-)[from U(p, X), E=480 MeV]; measured Eγ, Iγ, γγ-coin, γγ(θ), βγγ-coin; deduced logft, β-feeding intensities. ³⁴Si; deduced levels, J, π, γ branching ratios, δ, mixing ratios. Comparison to calculations using configuration interaction shell-model method FSU and an ab-initio approach with the valence space in medium similarity renormalizarion group (VS-IMSRG). Systematics of the negative-parity states in the even-mass silicon isotopes (³⁰Si, ³²Si, ³⁴Si). GRIFFIN spectrometer consisting of 16 Compton suppressed HPGe clover detectors coupled with Scintillating Electron Positron Tagging ARray (SCEPTAR) consisting of ten plastic scintillator paddles and a 1 mm thin fast plastic scintillator - zero degree scintillator (ZDS) at the TRIUMF-ISAC facility.
