E2 transitions in {sup 30}Si are investigated in relation to intrinsic deformations based on a method of antisymmetrized molecular dynamics. By comparing E2 transition strengths in the mirror nuclei {sup 30}Si and {sup 30}S, transition matrix amplitudes M{sub p} and M{sub n} for protons and neutrons are discussed in mirror analysis. Particular attention is paid to the M{sub n}/M{sub p} ratio in the transition from the 2{sub 2}{sup +} state to the 0{sub 1}{sup +} state. The M{sub n}/M{sub p} ratio in {sup 26}Mg and {sup 26}Si is also investigated. It is found that the proton dominance in the transition 2{sub 2}{sup +}{yields}0{sub 1}{sup +} in {sup 30}Si and {sup 26}Si originates in the oblate trend of the Z=14 proton structure.
