The differential cross-section for the elastic scattering of He4 particles on Be9 has been studied in the bombarding energy range 1.4-2.5 MeV.
The excitation functions for the elastically scattered α-particles from Be9 were measured at six angles 90°, 125°, 132°, 140°, 150° and 160° in the centre of mass system.
A clear and pronounced resonance is observed in the measured cross-section at incident α-particle energy 1.93 MeV. Analysis of the data in terms of the single level approximation theory leads to the assignment Jπ = 5+/2 for the observed resonance. Reduced and partial widths for elastic scattering were determined.
