In this paper, we report on neutron elastic and inelastic experiments from the sd-shell nuclei . 28S r., 32S and 34S. The measured elastic and inelastic differential cross sections at 21.7 MeV for the nuclei “Si, “S, and 34S, and at 25.5 MeV for 34S are analyzed in terms of three collective models: rotational, vibrational, and rotation-vibration. The paper is organized as follows: In sect. 2, the experimental set-up used during the measurements is described together with the data reduction process. The 28Si(n, n’)“Si reaction at 21.7 MeV is studied by means of rotational, vibrational, and rotation-vibration models in sect. 3. The coupling schemes include the g.s., 2: (E, = 1.78 MeV), 4: (E, = 4.62 MeV), and 3, (E, = 6.88 MeV) states.

N2 - Differential cross sections for the elastic and inelastic scattering of neutrons from the sd-shell nuclei 28Si, 32S and 34S have been measured in the 20-26 MeV region. The data are analyzed in terms of the rotation-vibration (28Si) and anharmonic vibration (32, 34S) collective models. Isoscalar E2, E3 and E4 transition matrix elements are obtained from the normalized multipole moments of the real potential and the results are compared with those obtained from electromagnetic probes and from nuclear structure theoretical calculations.
