	abstract = {The g factors of the 21/+ and 31/- states in semi-magic 90Zr have been measured for the first time with the technique of Coulomb excitation of 90Zr beams in inverse kinematics in combination with transient magnetic fields. The resulting g factors, g(21/+) = +1.25(21) and g(31/3) = +0.986(56), are both consistent with a dominant g(9/2) proton configuration and a closed N = 50 neutron shell. The lifetime of the 21/+ state was measured by the Doppler shift attenuation method, ? = 0.126(3) ps. (C) 2000 Elsevier Science B.V.},
