Description

We studied the energy dependence of the excitation of the ''1ℎω,'' Jπ=6-, state in the 28Si(p,n)28P(4.95 MeV) reaction and the ''0ℎω,'' Jπ=9+, state in the 88Sr(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 88Sr to the 28Si DWIA normalizations is independent of beam energy, indicating that the systematic difference in DWIA normalizations reported earlier between 0ℎω and 1ℎω 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
