A measurement of the 1{ital s}2{ital p} {sup 1}{ital P}{sub 1}{r arrow}1{ital s}{sup 2} {ital S}{sub 0} resonance transition in heliumlike germanium (Ge{sup 30+}) has been made on the Lawrence Livermore National Laboratory electron-beam ion trap to a precision of 21 ppm. The result is compared with theoretical values and confirms a trend previously seen in the differences between experiment and theory for this transition as a function of {ital Z}. Results for the 1{ital s}2{ital p} {sup 3}{ital P}{sub 1}{r arrow}1{ital s}{sup 2} {ital S}{sub 0} and 1{ital s}2{ital p} {sup 3}{ital P}{sub 2}{r arrow}1{ital s}{sup 2} {ital S}{sub 0} intercombination lines and for the 1{ital s}2{ital s} {sup 3}{ital S}{sub 1}{r arrow}1{ital s}{sup 2} {sup 1}{ital S}{sub 0} forbidden line are also presented and show similar differences with theoretical predictions.
