Low-spin excitations in ⁹⁷Zr

NUCLEAR REACTIONS ⁹⁶Zr(n, γ), E=cold or thermal; measured Eγ, Iγ, γγ-coin, γγ(θ) using the EXILL HPGe array at the PF1B cold-neutron facility of ILL, Grenoble. ⁹⁷Zr; deduced levels, J, π, multipolarities, mixing ratios, S(n), configurations. Comparison with previous experimental values. ²⁷Al, ³⁵Cl, ⁹¹Zr(n, γ), E=cold or thermal; measured Eγ, Iγ, data used for calibration purpose. ²⁸Al, ^92,97Zr; deduced S(n) and compared with literature values.

RADIOACTIVITY ^97,97mY(β^-)[from ²³⁵U(n, F) using Lohengrin fission-fragment separator of the ILL]; measured Eγ, Iγ, γγ-coin, γγ(θ), γγ(linear polarization) using the EXILL Ge array. ⁹⁷Zr; deduced levels, J, π, multipolarities, mixing ratios. ⁹⁷Sr, ⁸⁸Br(IT); measured isomer half-lives of 830-keV isomer in ⁹⁷Sr, and 270-keV isomer in ⁸⁸Br by γ(t).
