Inelastic 9Be + α scattering at 90 MeV: Whether the concept of the 9Be structure should be changed?

Inelastic 9Be + α scattering at 90 MeV: Whether the concept of the 9Be structure should be changed?

Experimental data on inelastic 9 Be+α scattering induced by 90-MeV α particles are analyzed. The 2.78-MeV excited state is shown to have spin–parity of I π =1/2 - in agreement with the existing data. For the 4.70-MeV excited state, it is impossible to make an unambiguous choice between the previous...

Zusammenfassung:Experimental data on inelastic 9 Be+α scattering induced by 90-MeV α particles are analyzed. The 2.78-MeV excited state is shown to have spin–parity of I π =1/2 - in agreement with the existing data. For the 4.70-MeV excited state, it is impossible to make an unambiguous choice between the previous value I π = 3/2 + , and the proposed new value I π = 1/2 − .
