Measurements of Coulomb excitation probabilities of the first 2{sub 1}{sup +} state of {sup 100,102,104}Ru were carried out using back-scattered ions of {sup 4}He and {sup 16}O. The static quadrupole moments Q{sub 2{sub 1}{sup +}} and the reduced transition probabilities B(E2;0{sub 1}{sup +}{r_arrow}2{sub 1}{sup +}) have been determined using the reorientation effect. The quadrupole moments Q{sub 2{sub 1}{sup +}} deduced for the positive sign of the 2{sub 2}{sup +} interference term are {minus}0.54{plus_minus}0.07 eb, {minus}0.64{plus_minus}0.05 eb, {minus}0.62{plus_minus}0.08 eb for {sup 100}Ru, {sup 102}Ru, and {sup 104}Ru, respectively. The reduced transition probabilities B(E2;0{sub 1}{sup +}{r_arrow}2{sub 1}{sup +}) are 0.493{plus_minus}0.003 e{sup 2}b{sup 2}, 0.614{plus_minus}0.004 e{sup 2}b{sup 2}, and 0.809{plus_minus}0.006 e{sup 2}b{sup 2}, respectively. A compilation of the available experimental results for the reduced eletric quadrupole transition probability B(E2;0{sub 1}{sup +}{r_arrow}2{sub 1}{sup +}) and for the static quadrupole moments Q{sub 2{sub 1}{sup +}} for the even ruthenium stable isotopes (96{le}A{le}104) are presented. {copyright} {ital 1998} {ital The American Physical Society}
