Abstract

Inelastic scattering of 480 MeV and 340 MeV α particles on 208Pb, 116Sn and 58Ni has been used in a search for high excitation energy giant multipole resonances, up to E* = 60 MeV for 208Pb and E* = 45 MeV for 116Sn and 58Ni. Above the well known quadrupole and monopole resonances, there is clear evidence for a very wide set of negative parity modes (including the already known high energy octupole), followed and mixed with another very wide set of positive parity resonances, extending up to the limits of the experimental spectra.

Abstract

The angular distributions of the inelastic scattering of antiprotons for a few collective states of 12C and 18O have been measured. They exhibit a diffractive pattern, typical of strong absorption. Coupled channel analysis of these data has been carried out. The derived multipole moments agree fairly well with those obtained with other probes. Microscopic calculations performed in the framework of the DWIA formalism, using either the Paris or the Dover-Richard NN interaction are in good agreement with the data for the low-lying collective states. The present status of the experimental study of the unnatural parity levels is discussed.

Abstract

Angular distributions for elastic scattering of antiprotons from nuclei are analyzed in terms of a fuzzy black disk model. Data from /sup 12/C, /sup 16/O, /sup 18/O, and /sup 40/Ca at incident antiproton energies of 47 and 180 MeV are analyzed. The obtained fits are qualitatively good concerning the slope and position of the extrema, but are too deep in the minima.

Abstract

Angular distributions of cross section, and A y and A yy analysing powers were measured for polarised deuteron elastic scattering from 16 O at 200, 400 and 700 MeV. The data at 200 MeV bear evidence of the nuclear rainbow phenomenon while those at 400 and 700 MeV are reminiscent of the proton scattering results at equivalent energies. The data were analysed in terms of the optical model. The real central potential shape changes from an attractive Woods-Saxon form at 200 MeV to a wine-bottle-bottom form with a repulsive interior at 700 MeV. The total reaction cross sections deduced display a clear nuclear transparency effect in the present energy domain in agreement with predictions from the Glauber theory optical limit. Comparison with previous results for 40 Ca and 58 Ni targets is made.

Abstract

Thanks to an experimentation, this research studies the effects of two broadcast sponsorships on implicit attitude toward a new brand. This brand sponsors two quasi-identical broadcasts differentiated only by their emotional content. To be ecologically valid, the experiment records the attitudinal effects one week later when the subjects don't remember the exposition phase any more and cannot explicitly recognize the brand. The attitude is then implicit. The impact of humorous broadcast sponsorship (with two exposures) on implicit attitude toward the brand is manifest and positive. The sad broadcast has no implicit effects: this type of TV sponsorship has been inefficient. The results are explained with the familiarity-misattribution model. At least, practical suggestions are proposed.

Angular distributions of p- 4 He elastic scattering differential cross sections have been measured at 350, 650, 1050 and 1150 MeV, in regions of four-momentum transfer squared t = 0.02–0.71 (GeV/ c ) 2 . These new measurements confirm the absence of a pronounced first diffraction minimum. New theoretical analyses are also presented.

Abstract

Antiproton-carbon elastic and inelastic scattering cross sections have been measured at 46.8 MeV over an angular range 6° ⩽ θ ⩽ 59° with a magnetic spectrometer. Fits to the elastic and inelastic 4.44 MeV excited state cross sections put realistic limits on the strengths of the real and imaginary parts of the antiproton-carbon optical potential. The continuum cross section due to carbon break-up appears to be smaller than it is for corresponding proton data.

Abstract

Angular distributions for elastic scattering of 180 MeV antiprotons from 12C, 40Ca, and 208Pb have been measured over a wide angular range with a magnetic spectrometer. In general, microscopic calculations agree fairly well with the data. Optical-model fits with Woods-Saxon parametrization determine the magnitude and the relative strength of the real and imaginary potentials at the nuclear surface. When the shape of the potentials is derived from that of the charge distribution, the depth of the real potential is found to be shallow (30 MeV < V0 < 70 MeV). These results are in some disagreement with several models and predictions, but are consistent with the results of p-12C scattering at 46.8 MeV and with a recent a analysis of p-atom data.

Abstract

12 C + 12 C elastic scattering has been measured at E / A = 120 MeV / u and 200 MeV / u . Large surface transparency is observed which allows to determine the potential value down to small internuclei distance ( R ∼ 3 fm ). A phenomenological analysis of the results shows the onset of a large transparency at higher energy. The real potential strength is found to decrease rapidly with the increasing incident energy, whereas a similar decrease of the imaginary part at the sensitive distance is combined with an increase of the diffuseness.

Abstract

Elastic scattering of 288,340,480 and 699 MeV Alpha -particles was measured on 208 Pb, 116 Sn and 58 Ni. The data were analysed in terms of a phenomenological optical model. The optical potentials obtained were found to vary consistently with the target nucleus and the incident energy. The radial zone where the potentials are well determined was studied in detail. The data for 208 Pb were also analysed with a folding model. The energy dependence of the strong-absorption radius and of the reaction cross section shows that the nuclear surface becomes slightly transparent for incident energies above 150 MeV per nucleon.
