Reexamined lifetimes of the low-lying states of ⁸⁶Zr by recoil distance differential decay measurements

NUCLEAR REACTIONS ⁷³Ge(¹⁶O, 3n)⁸⁶Zr, E=57 MeV; measured Eγ, Iγ, γγ-coin, level half-lives by recoil distance Doppler shift method and DDCM analysis, using the ROSPHERE detector array of 15 HPGe detectors with BGO shields and nine LaBr₃(Ce) detectors at the HH-NIPNE-Bucharest tandem accelerator facility. ⁸⁶Zr; deduced levels, J, π, B(E2), B(M1), B(E1). Comparison with theoretical calculations using IBM-1 model, IBM-1 model with broken pairs, and shell-model. Comparison with previous experimental data in the ENSDF database.
