It is shown that the existing yrast B(E2) values [especially the B(E2;4{sub 1}{sup +}{yields}2{sub 1}{sup +})/B(E2;2{sub 1}{sup +}{yields}0{sub 1}{sup +}) ratio] in {sup 98}Ru are highly anomalous and cannot be plausibly interpreted with existing models. A survey of all even-even nuclei from 40{<=}Z{<=}80 shows that this phenomenon is rare in collective nuclei. It occurs to a much lesser extent in {sup 114}Te, {sup 114}Xe, and possibly a few other nuclides. The combination of vibrational-like energies and nonvibrational B(E2) values perhaps points to a different kind of vibrational behavior.
