Energy levels of light nuclei A=11☆

Energy levels of light nuclei A = 3

An evaluation of A =1 8-19 was published in Nuclear Physics A595 (1995), p. 1. This version of A =1 9differs from the published version in that we have corrected some errors discovered after the article went to press. It has also been slightly revised as of June 13, 2000 to include hyperlinks for references and tables. Figures have been omitted from this manuscript. Also, Reference key numbers are in the NNDC/TUNL format.

Energy Levels of Light Nuclei A =1 9

The results on the differential cross section of dp elastic scattering obtained at the Internal Target Station at the Nuclotron JINR at the energies of 500, 750 and 900MeV/nucleon are presented. The measurements have been performed using an unpolarized deuteron beam and polyethylene foil target. The data have been obtained in the angular range of $ 70^{\circ}$ - $ 120^{\circ}$ in the cms. The angular dependences of the data from the present experiment are compared with the world experimental data obtained at nearby energies as well as with the theoretical calculations performed within the relativistic multiple scattering theory. The behavior of the differential cross section at the fixed scattering angles covering the total cms energy region of $ \sqrt{s} = 3.1 -3.42$ GeV is in qualitative agreement with the s power-law dependence.

The differential cross section in deuteron-proton elastic scattering at 500, 750 and 900 MeV/nucleon

ALL at small momentum transfers for the first complete determination of the forward pp scattering amplitudes

The asymmetry ${A}_{\mathrm{NN}}$ for pp elastic scattering has been measured at 800 and 650 MeV in the region of Coulomb-nuclear interference. The data have been analyzed to extract the real part of a spin-spin scattering amplitude. Results are compared with the predictions of forward dispersion relations. They disagree significantly at 650 MeV.

First measurement of the real part of a pp double-spin-flip amplitude.

The elastic scattering of 800 MeV polarized protons, with longitudinal, normal, and sideways orientations, from deuterons polarized normal to the scattering plane has been measured. The four-momentum transfer interval measured in this experiment is from 0.03 to 0.17 (GeV/c)/sup 2/. Spin-correlation and spin-transfer observables have been extracted from the data. This experiment is one of a series designed to determine a number of observables in excess of the minimum number required to reconstruct the 12 subamplitudes of the proton-deuteron elastic scattering amplitude directly from spin observables. A comparison of the data with theoretical calculations employing three different phase-shift solutions for NN amplitudes reveals that sizable ambiguities exist in the values of NN amplitudes at small momentum transfers.

Spin observables in small-angle elastic p

The asymmetries ${A}_{\mathrm{NN}}$ and ${A}_{\mathrm{LL}}$ have been measured at small angles for the p\ensuremath{\rightarrow} p\ensuremath{\rightarrow}\ensuremath{\rightarrow}d${\ensuremath{\pi}}^{+}$ reaction at 650 and 800 MeV. Now complete angular distributions are integrated to obtain the contribution of this channel to \ensuremath{\Delta}${\ensuremath{\sigma}}_{L}$. These contributions are combined with those from the elastic channel to determine \ensuremath{\Delta}${\ensuremath{\sigma}}_{L}$(p\ensuremath{\rightarrow} p\ensuremath{\rightarrow}\ensuremath{\rightarrow}NN\ensuremath{\pi}) at 650 (=0.775\ifmmode\pm\else\textpm\fi{}0.5 mb) and 800 (=-1.52\ifmmode\pm\else\textpm\fi{}0.6 mb) MeV. There is pronounced disagreement between these data and the predictions of conventional theories. ${A}_{\mathrm{NN}}$ and ${A}_{\mathrm{LL}}$ also compared with theoretical predictions and their influence on partial-wave analyses is discussed.
