Angular distributions of proton elastic and inelastic scattering leading to the 3.04, 2.43, and 1.75-Mev states in Be/sup 9/ were measured at 6.1 to 7.3 Mev. The background subtraction was carried out giving attention to the 3.04Mev state. No remarkable energy dependence of angular distributions is seen for the elastic scattering. All angular distributions of inelastic seattering show distinct forward peaks and change little with the proton energy. In the angalar distributions for the 2.43-Mev state gradual but definite energy dependence can be recognized. These angular distributions are compared with the simple direct interaction theories. Results are consistent with the negative parity of the 3.04-Mev state and the positive parity of the 1.75-Mev state. Cross sections for the excitation of the 3.04, 2.43 and 1.75-Mev states are 22, 106, and 5 mb respectively, for 7.3-Mev protons. Inelastic scattering leading to these states in Be/sup 9/ occurs mainly via direct interaction process, and the contribution from the compound nucleus formation is small in the present energy region.
