Elastic differential cross sections and analyzing powers for p+40,42,44,48Ca at 0.8 GeV☆

Abstract Differential cross sections and analyzing powers for the elastic scattering of 800 MeV polarized protons from 40,42,44,48Ca are reported. A first-order, spin-dependent KMT optical potential analysis is presented from which the rms radii of the neutron densities are deduced. A comparison of these results with other determinations and with various theoretical predictions is given.

Elastic scattering of 0.8-GeV protons from C12, Ni58, and Pb208

Differential cross sections for elastic scattering of 0.8-GeV protons from /sup 12/C, /sup 58/Ni, and /sup 208/Pb have been measured. Preliminary analysis of the data in terms of the Kerman-McManus-Thaler formalism with spin-dependent nucleon-nucleon amplitudes shows sensitivity to details of proton and neutron matter distributions.

Elastic differential cross sections and analyzing powers for p + 54Fe, 58,64Ni at 800 MeV

Abstract Elastic scattering analyzing powers and differential cross sections for 800 MeV → p + 54Fe, 58,64Ni are reported. An approximately mode-independent technique is used to extract information concerning the neutron density distributions of these nuclei.

Analysis of elastic scattering of 0.8 GeV polarized protons from 116Sn and 124Sn

Abstract Differential cross section and analyzing power data for elastic scattering of 0.8 GeV polarized protons from 116Sn and 124Sn are analyzed in terms of a spin-dependent Kerman-McManus-Thaler formalism. Neutron matter densities and rms radii are deduced with careful attention to sources of error, and found to be in good agreement with Hartree-Fock predictions.

p-4He elastic scattering at 788 MeV

Abstract The p- 4 He elastic cross section at 788 MeV has been measured for laboratory angles between 13.3° and 165.5° corresponding to a range of four-momentum-transfer, − t , from 0.11 to 4.19 GeV 2 / c 2 . Evidence is presented for a backward diffraction-like structure not previously observed (3.4 t 2 / c 2 ). In the region (1.6 t 2 / c 2 ) a smooth fall off from the shoulder due to triple scattering is observed with no evidence for quadrupole scattering.

Quasi‐elastic scattering of 800 mev protons and the detection of alpha particle and deuteron clusters in nuclei

A survey of quasi-elastic scattering of 800 MeV protons was carried out at LAMPF using the high resolution spectrometer, and targets of /sup 6/Li, Li, /sup 12/C, /sup 27/Al, /sup 40/Ca, /sup 51/V, /sup 90/Zr and Pb. Measurements were made at angles of 5, 7, 9, 11, 13, 15, 25, and 30/sup 0/. Absolute cross sections were obtained using known (p,p) elastic cross sections. The momentum spectra were taken from the elastic region to well beyond the quasielastic peak. The variation in peak cross section and the FWHM of the peaks with mass number is reported. Evidence is presented for the quasielastic scattering of protons from clusters of mass 4 in the nucleus. 2 references.
