Coulomb Excitation of the Even Tin Nuclei

Coulomb excitation of the first 2+ states of the even tin nuclei was produced by 10-MeV $\alpha$ particles to obtain accurate $B\left(E2\mathrm{}\right)\mathrm{}$ values (relative error ± 2%, absolute error ± 5%). The experimental $B\left(E2\mathrm{}\right)\mathrm{}$ values are compared with the values calculated by Kisslinger and Sorensen and by Uher and Sorensen. The Uher-Sorensen $B\left(E2\mathrm{}\right)\mathrm{}$'s are in appreciably better agreement with the experimental results than are the Kisslinger-Sorensen ones.
