“…The adopted S-factors are based on (z, d) data [104] only. The (d, n) [105][106][107][108], (~, t) [109] and other (z,d) [110] results did not meet one or more of the requirements mentioned above. For the yrast levels MSDI and ASDI give very similar S-factors in good agreement with experiment.…”

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.

“…Okorokov [1], [2], [3] was the first to suggest that all of the above requirements are met best in Coulomb interaction of a high-energy particle propagating in a crystal along the crystallographic axis. Here the rôle of "time" is played by the crystal thickness L. In [1] the resonant excitation of atoms and nuclei by a periodical Coulomb field of a crystal was predicted.…”

“…Here the rôle of "time" is played by the crystal thickness L. In [1] the resonant excitation of atoms and nuclei by a periodical Coulomb field of a crystal was predicted. In [2] the first observation of the resonant transition of He + (n = 1) to He + (n = 4) in Ag crystal was reported. For a propagation through a crystal with the lattice spacing d, the frequency ν = 2πv/d, where v is the velocity of the atom.…”

We study coherent enhancement of Coulomb excitation of high energy particles in crystals. We develop multiple scattering theory description of coherent excitation which consistently incorporates both the specific resonant properties of particle-crystal interactions and the final/initial state interaction effects typical of the diffractive scattering. Possible applications to observation of induced radiative neutrino transitions are discussed.

2014 Les énergies d'excitation, les facteurs spectroscopiques et les propriétés électromagnétiques des 11 premiers états de 61Cu et 63Cu sont comparés aux prédictions d'un modèle de couplage coeur-particule. Les états de quasi-particule d'un proton se trouvant dans les couches If 7/2, 2p3/2, If5/2 et 2p1/2 sont couplés aux états à un et deux phonons du c0153ur de nickel. Contrairement à certains calculs effectués antérieurement, où certains paramètres pouvaient varier librement, nous avons considéré, en particulier pour la constante de couplage et les énergies de quasi-particule, des valeurs conformes aux systématiques existantes. Nous avons ainsi obtenu un meilleur accord général entre l'expérience et la théorie. Abstract. 2014 The excitation energies, spectroscopic factors and electromagnetic properties of the first eleven levels in 61Cu and 63Cu are compared with the predictions of a particle-core coupling model, described as a proton in the 1f7/2, 2p3/2, 1f5/2 and 2p1/2 quasi-particle states, coupled to the one and two-phonon states of the Ni-core. Considering values for the coupling constant and the quasi-particle énergies in agreement with the existing systematics of this mass region, the overall agreement between calculated and observed properties is good and, in fact, better than in previous calculations containing free parameters.
