    "abstract": "In the no-core shell model formalism we compute effective one- and two-body\noperators, using the Lee-Suzuki procedure within the two-body cluster\napproximation. We evaluate the validity of the latter through calculations in\nreduced model spaces. In particular, we test the results for the two-body\nsystem and find that indeed the effective operators in the reduced space\nreproduce the expectation values or transition strengths computed in the full\nspace. On the other hand, the renormalization for operators in the case of 6Li\nis very weak, suggesting the need for higher-body clusters in computing the\neffective interaction.",
