Intermediate-spin states of ⁹²Zr and a large B(E2) value between the 10⁺₁ and 8⁺₁ states

NUCLEAR REACTIONS ⁹Be(⁸⁶Kr, 3n), E=280 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ)(ADO), half-life of 10+ state by DSAM using an array of 12 Compton-suppressed HPGe detectors at the Tandem accelerator facility of the Japan Atomic Energy Agency (JAEA). ⁹²Zr; deduced high-spin levels, J, π, multipolarities, B(E2). Systematics of level energies in ^{90,92,94,96,98,100}Zr and N=52 even-A isotones. Discussed possible origin of collectivity based on a phenomenological deformed rotor model.
