Observation of a large β-delayed neutron emission component in ¹⁰²Rb decay and identification of excited states in ¹⁰²Sr

RADIOACTIVITY ¹⁰²Rb(β^-), (β^-n)[from U(p, F), E=500 MeV at TRIUMF-ISAC facility]; measured Eβ, Eγ, Iγ, βγ-, γγ-coin using 8π array for γ detection and SCEPTAR plastic scintillator for β detection. ^102,102Sr; deduced levels, J, π, delayed neutron-emission probability P_n. Systematics of absolute intensity of the first 2+ to 0+ transition, and direct ground-state feeding in β-delayed neutron emission in the β decays of ^{94,96,98,100,102}Rb. Plots of P_n/T_1/2 versus Q_βn for decays of ^{94,96,98,100,102}Rb, and comparison with theoretical and phenomenological descriptions. ¹⁰²Zr, ¹⁰²Sr, ¹⁰¹Zr(β^-); observed γ rays.
