In-beam γ-ray spectroscopy of the neutron-rich platinum isotope ²⁰⁰Pt toward the N=126 shell gap

NUCLEAR REACTIONS ¹⁹⁸Pt(⁸²Se, ⁸⁰Se)²⁰⁰Pt, E=426 MeV; measured Eγ, Iγ, (⁸⁰Se recoils)γγ-coin using PRISMA spectrometer for ⁸⁰Se recoils and AGATA array for Doppler-corrected γ rays at XTU Tandem-ALPI accelerator of LNL-Legnaro facility. ²⁰⁰Pt; deduced levels, J, π, ground-state band, structure above the 17-ns, 7- isomer. Comparison with theoretical model calculations.

NUCLEAR STRUCTURE ^{190,192,194,196,198,200,202,204}Pt; calculated particle-number-projected potential energy surfaces in (β₂, γ) plane, yrast band excitation energies. Beyond mean-field, symmetry-conserving configuration-mixing (SCCM) calculations based on Gogny D1S energy density functionals. Comparison with experimental data.
