NUCLEAR REACTIONS ⁶⁰Ni, ²⁰⁸Pb(⁹⁸Sr, ⁹⁸Sr'), E=276.3 MeV; ¹⁰⁹Ag, ¹²⁰Sn(⁹⁶Sr, ⁹⁶Sr'), E=275.5 MeV; measured Eγ, Iγ, scattered Sr ions and target recoils, (particle)γ-coin, γ(θ), differential Coulomb excitation cross sections using Miniball array for γ detection and Si strip detectors for ions at REX-ISOLDE-CERN facility. ^96,98Sr; deduced levels, E2 and M1 matrix elements, B(E2) and level half-lives, quadrupole moments and deformation parameters, E0 monopole transition strengths using GOSIA2 analysis. Comparison with previous experimental data and five-dimensional collective Hamiltonian and Gogny D1S force, and using complex excited VAMPIR approach. Systematics of level energies, transitional and spectroscopic quadrupole moments in ^94,96Kr, ^96,98Sr, ^98,100Zr, ^100,102Mo. Systematics of energy and B(E2) for first 2+ state, and energies of second 0+ states in ^{90,92,94,96,98,100,102}Sr. ⁶⁰Ni, ²⁰⁸Pb(⁹⁸Rb, ⁹⁸Rb'), E=276 MeV; measured Eγ, Iγ, scattered Rb ions and target recoils, (particle)γ-coin, γ(θ), level half-lives by recoil-distance Doppler shift method. ⁹⁸Rb; deduced levels.
