Simple approximation for the starting-energy-independent two-body effective interaction with applications to 6Li
D. C. Zheng, B. R. Barrett, J. P. Vary +1
We apply the Lee-Suzuki iteration method to calculate the linked-folded diagram series for a new Nijmegen local NN potential. We obtain an exact starting-energy-independent effecti…
Perturbative Gluon Shadowing in Heavy Nuclei
K. J. Eskola, Jianwei Qiu, Xin-Nian Wang
We study how much gluon shadowing can be perturbatively generated through the modified QCD evolution in heavy nuclei. The evolution of small- gluons is investigated within the s…
Minimizing Effective Many-Body Interactions
B. R. Barrett, D. C. Zheng, R. J. McCarthy +1
A simple two-level model is developed and used to test the properties of effective interactions for performing nuclear structure calculations in truncated model spaces. It is shown…
Exact Solutions of Model Hamiltonian Problems with Effective Interactions
D. C. Zheng, J. P. Vary, B. R. Barrett
We demonstrate with soluble models how to employ the effective Hamiltonian approach of Lee and Suzuki to obtain all the exact eigenvalues of the full Hamiltonian. We propose a new…
