“…The analysis of the spectra yielded the 7-decay scheme of 298i which is displayed in Figs [13] should be placed at 8,297 KeV excitation energy in reasonable agreement with our work and E~ = 8,291 KeV quoted in [14].

Particle y-ray coincidences have been measured in the 28Si (d, py) reaction at 6.5 and 7 MeV bombarding energy, in the 26Mg (c~, ny) reaction at 12, 14 and 15 MeV, and in the 27A1 (z, py) reaction at 9 MeV. The ;~-decay has been observed for all bound states of 29Si and for 56 unbound states up to 12,960 KeV excitation energy. Particle ?;-ray angular correlations were measured in the 2ssi (d, pT) reaction at 6.5 MeV and in the 26Mg (cg nT) reaction at 12 MeV. Spin (-parity) assignments or restrictions were obtained for nearly all bound states and some high-spin states above the binding energy. The assignment of mirror levels in 29Si and 29p has been extended to 8.2 MeV excitation energy. The excitation energies of 41 positive-parity states are reproduced by shell model calculations. The possible existence of a K~=5/2 + band with prolate deformation is discussed.

“…Secondly, the energy position of each state does not vary essentially with the increasing N . Thirdly, the energy position of 5/2 + state decreases while moving from 35 Si to 37 Si. The states of positive spin-parity may be assumed to be of collective origin and related with the (3/2 + ) − ν configuration.…”

Evolution of single-particle structure of silicon isotopes

Abstract. New data on proton and neutron single-particle energies E nlj of Si isotopes with neutron number N from 12 to 28 as well as occupation probabilities N nlj of single particle states of stable isotopes 28,30 Si near the Fermi energy were obtained by the joint evaluation of the stripping and pick-up reaction data and excited state decay schemes of neighboring nuclei. The evaluated data indicate following features of single-particle structure evolution: persistence of Z = 14 subshell closure with N increase, the new magicity of the number N = 16, and the conservation of the magic properties of the number N = 20 in Si isotopic chain. The features were described by the dispersive optical model. The calculation also predicts the weakening of N = 28 shell closure and demonstrates evolution of bubble-like structure of the proton density distributions in neutron-rich Si isotopes.PACS. 21.10.Pc Single-particle levels and strength functions -24.10.Ht Optical and diffraction models
