Inelastic α scattering from 20Ne

Cross sections for 20Ne(α,α1,2,3) were measured from Eα=5.6 (α1), 7.5 (α2), and 9.5 (α3) MeV up to 11.0 MeV in steps of 10 and 15 keV at up to 20 angles. The α1 data were fitted with a Legendre polynomial expansion, thus allowing limits to be placed on the spin and parity of 31 levels in 24Mg, about five of which have not previously been seen in elastic α scattering. In the α2 data some 15 levels are identified as to energy and width
