NUCLEAR REACTIONS ¹⁹⁷Au(¹⁴N, 4n)²⁰⁷Rn, E=78 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ). ²⁰⁷Rn; deduced levels, J, π, δ, high-spin states, directional correlation of oriented states (DCO) ratio, configurations, rotational-like band, collective oblate band; calculated levels J, π, quadrupole and triaxial deformation parameters. Large-scale shell-model calculations and the microscopic three-dimensional tilted axis cranking covariant density functional theory (3DTAC-CDFT) calculations. Systematic of bands structure and excited states for ²⁰⁵Pn, ²⁰⁷Rn, ²⁰⁹Ra. Array of 9 BGO-Compton-suppressed HPGe detectors, 2 LEP HPGe detectors, and 1 clover detector at HI-13 tandem accelerator at the China Institute of Atomic Energy (CIAE, Beijing).
