E2−E4Interference for (α, α′) Reactions

Although Coulomb-nuclear interference is certainly not a misnomer for the description of recently observed interference structure for $\alpha$-particle excitation of $4^{+}$ states in permanently deformed nuclei, the details of the interference are shown to be more easily understood as interference between $L=2\mathrm{}$ and $L=4\mathrm{}$ amplitudes.
