Tests of collectivity in ⁹⁸Zr by absolute transition rates

NUCLEAR REACTIONS ⁹⁶Zr(¹⁸O, ¹⁶O)⁹⁸Zr, E=50 MeV; measured recoiling light fragments using an array of six solar cells, Eγ, Iγ, (particle)γ-coin, level half-lives by Doppler-shift recoil-distance (RDDS) method and analysis by differential decay curve method (DDCM) using an array of 11 HPGe detectors and Cologne Plunger device at the Cologne 10 MV FN Tandem accelerator. ⁹⁸Zr; deduced levels, J, π, B(E2). Comparison with Monte Carlo shell model (MCSM), and interacting boson model with configuration mixing (IBM-CM) calculations, and with previous experimental data. Systematics of energies and B(E2) values of the first 2+ states in ^{90,92,94,96,98,100}Sr, ^{92,94,96,98,100,102,104,106}Zr.
