Background: The B(E2) transition strength to the 2+_2 state in 94Zr wasinitially reported to be larger by a factor of 1.63 than the one to the 2+_1state from lifetime measurements with the Doppler-shift attenuation method(DSAM) using the (n,n'gamma) reaction [E. Elhami et al., Phys. Rev. C 75,011301(R) (2007)]. This surprising behavior was recently revised in a newmeasurement by the same group using the same experimental technique leading toa ratio below unity as expected in vibrational nuclei. Purpose: The goal is anindependent determination of the ratio of B(E2) strengths for the transitionsto the 2+_(1,2) states of 94Zr with inelastic electron scattering. Method: Therelative population of the 2+_(1,2) states in (e,e') reactions was measured atthe SDALINAC in a momentum transfer range q = 0.17 - 0.51 fm^(-1) and analyzedin plane-wave Born approximation with the method described in A. Scheikh Obeidet al., Phys. Rev. C 87, 014337 (2013). Results: The extracted B(E2) strengthratio of 0.789(43) between the excitation of the 2+_1 and 2+_2 states of 94Zris consistent with but more precise than the latest (n,n'gamma) experiment.Using the B(E2) transition strength to the first excited state from theliterature a value of 3.9(9) W.u. is deduced for the B(E2; 2+_2 -> 0+_1)transition. Conclusions: The electron scattering result independently confirmsthe latest interpretation of the different (n,n'gamma) results for thetransition to the 2+_2 state in 94Zr.
