The measurements and explanations of g(I>2) factors are still a challenge for experiments and theory.<\/p>\n<p><strong>Purpose:<\/strong> Measurement of the g(2<sub>1<\/sub><sup>+<\/sup>) and g(4<sub>1<\/sub><sup>+<\/sup>) factors, the latter for the first time, in the  <sup>96<\/sup><sub>44<\/sub>Ru nucleus. Comparison of the experimental results with calculations using the shell model and collective models.<\/p>\n<p><strong>Methods:<\/strong> The experiments made use of the transient field technique, using a Coulomb-excitation reaction in inverse kinematics. Large scale shell model calculations were performed; comparisons with previous theoretical predictions, using the tidal-wave model and the hydrodynamical model, were carried out.<\/p>\n<p><strong>Results:<\/strong> The values of g(2<sub>1<\/sub><sup>+<\/sup>)=+0.46(2) and g(4<sub>1<\/sub><sup>+<\/sup>)=+0.58(8) were experimentally obtained. While the g(2<sub>1<\/sub><sup>+<\/sup>) value agrees with the hydrodynamical model prediction of g=Z\/A=+0.46, the g(4<sub>1<\/sub><sup>+<\/sup>) is in agreement with the shell model predictions. The trend of the experimental g factors, as a function of nuclear spin, is not reproduced by the theoretical models discussed.<\/p>\n<p><strong>Conclusions:<\/strong> Measurements of g(2<sub>1<\/sub><sup>+<\/sup>) and g(4<sub>1<\/sub><sup>+<\/sup>) in <sup>96<\/sup>Ru were performed.
