One-neutron knockout reactions from the deeply bound N = 16 isotones with Z = 16, 17, and 18 have been studied in inverse kinematics with intermediate-energy beams. ␥-ray spectroscopy in coincidence with the detection of knockout residues allowed for an investigation of the one-neutron removal leading to individual excited states. Spectroscopic factors are deduced in the framework of the sudden and eikonal approximations and are compared to USD shell-model predictions. The momentum distributions observed in the experiment are used to identify the angular momentum l carried by the knockedout neutron by comparing with calculations based on a black-disk reaction model. The systematics of reduced single-particle occupancies attributed to the effect of short-range correlations, observed so far for stable and near-magic nuclei in ͑e , eЈp͒ and ͑d , 3 He͒ reactions and in one-nucleon knockout on light deeply bound systems, are extended in this work.

“…Recent heavy-ion work also suffers from bad resolution and, furthermore, the relevant normalization factors are still rather uncertain. From the selected data the spectroscopic strengths have been recalculated using Only one relevant case [83] has been found in which polarized protons have been used, so that the lf5/2 and l f% 2 contributions could be separated. In this case, 61Ni(p, d)6~ the f%2 strength leading to the first and second 2 + state in 6~ is found to be negligible.…”

Binding energies, excitation energies and spectroscopic factors have been calculated for 57-67Ni and 58-68Cu in an unrestricted (2p3/2, lJ;~2,2p1,2 ) shell-model space. The effective two-body matrix elements are obtained from the modified surface delta interaction (MSDI) and from a least-squares fit to experimental binding and excitation energies (ASDI). The average deviation between about 100 experimental and calculated energies is 0.14 MeV for MSDI and 0.08 MeV for ASDI. Excitation energies of high-spin states are given also. Spectroscopic factors have been calculated for all single-nucleon transfer reactions on stable Ni or Cu targets leading to Ni or Cu isotopes. For spectroscopic factors larger than 0.4 the average deviation between theory and experiment is about 30 %. The experimentally observed and calculated spectroscopic strengths are compared by using sum rules and are found to be consistent. An extensive compilation has been made of experimental data on energies, J~ assignments and spectroscopic factors.

“…Several reports of one neutron transfer studies on the Sn isotopes have been published already (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26), but most of these deal with isolated isotopes or just a few isotopes. While such reports are valuable as a consistency check of both experimental cross sections and extracted spectroscopic factors (Sj), there is clearly considerable importance attached to a systematic study, both experimentally and theoretically, over the whole of the Sn isotopic sequence.…”

Thc nuclear structure of the cvcn and odd tin isotopcs has been studied by 20 MeV (p,d) reactions. States strongly populated in thc odd isotopcs arc due to the valcncc neutron shells and cxtcnd up to only 2 MeV of excitation cncrgy; "deep hole" states were not identified. Thc occupation probabilities extracted from finite-range distorted-wave-Born-approxin~ation calculations generally agree well with the predictions of the BCS theory of supcrconducting nuclei, particularly with the calculations of Clcmcnt and Barangcr. In the cvcn tin isotopes. strongly populated states arc characterized predominantly by L = 2 transfers extending up to 4 MeV excitation energy. Thc experimental spectroscopic factors for transitions populating even final states arc comparcd with the BCS calculatcd values of Clement and Baranger, Alzetta and Sawicki, and Van Gunstercn; relatively good agreement is obtained for L = 2 transitions, but not for L = 0 transitions. A considerable fraction of the expected sum iule L = 2 strength in "%n is missing in the ""Sn(p,d)"%n cxpcrimcntal spectrum; in like manner, no 4+ strength could be identified in either "'Sn or IlXSn.La structure nuclCairc des isotopes pairs ct imparis dc I'Ctain a CtC CtudiCc au moyen des rCactions (p,d) ii 20 MeV.
