Transition from collectivity to single-particle degrees of freedom from magnetic moment measurements on ⁸²₃₈Sr₄₄ and ⁹⁰₃₈Sr₅₂

NUCLEAR MOMENTS ^82,90Sr, ^78,86Kr; measured precession angles, g factors of first 2+ and 4+ states, second 2+ state in ⁷⁸Kr by transient-field technique in Coulomb excitation and α-pickup reaction at K500-TAMU cyclotron facility. Comparison with shell-model calculations and previous experimental results. Systematics of g factors of first 2+ states in even-even nuclei with Z=30-48, N=30-70. Discussed proton subshell closures at Z=38 and Z=40.
