Neutron-proton multiplets in the odd-odd nucleus⁹⁰₃₇Rb₅₃

NUCLEAR REACTIONS ²³⁵U(n, F), E=cold neutrons; measured Eγ, Iγ, γγ-coin, γγ(θ), level half-lives, γγγ-coincidences between transitions from ⁹⁰Rb and from complementary fission fragments ¹⁴³Cs and ¹⁴⁴Cs using EXOGAM array at ILL-Grenoble. ⁹⁰Rb; deduced medium-spin levels, J, π, multipolarities and mixing ratios, configurations, seniority-3 coupling in N=53 isotones and its absence in N=51 isotones. Comparison with shell-model calculations.

NUCLEAR STRUCTURE ^88,90Rb; calculated levels, J, π using shell-model. Comparison with experimental values.
