摘要：
The 2(1)(+) energies and B(E2; 0(1)(+) -> 2(1)(+)) values of even-even Sn nuclei with mass numbers between 102 and 130 have been calculated within the framework of the SD-pair approximation of the nuclear shell model. We employ monopole and quadrupole pairing plus quadrupole-quadrupole interaction with optimized parameters. Good agreement is obtained between the calculated results and experimental data. The robustness of our calculated 2(1)(+) level and E2 transition rates with respect to different sets of effective charge and different forms of the Hamiltonian is studied.
