N2 - We studied the energy dependence of the excitation of the ''1Latin small letter h with strokeω,'' Jπ=6-, state in the Si28(p,n)28P(4.95 MeV) reaction and the ''0Latin small letter h with strokeω,'' Jπ=9+, state in the Sr88(p,n)88Y(1.48 MeV) reaction at Ep=100, 200, 300, and 400 MeV. Differential cross sections for these reactions were measured and compared to distorted-wave impulse-approximation (DWIA) calculations. The ratio of the Sr88 to the Si28 DWIA normalizations is independent of beam energy, indicating that the systematic difference in DWIA normalizations reported earlier between 0Latin small letter h with strokeω and 1Latin small letter h with strokeω stretched states is a nuclear-structure effect. Additionally the DWIA normalization for each reaction is independent of the beam energy indicating that the necessary ingredients for DWIA calculations to describe these transitions consistently are well understood.
