PRODUCTION OF HIGH MOMENTUM NEGATIVE PIONS BY 800-MEV PROTONS AT 0-DEGREES TO 20-DEGREES

Barlow, D.B. ; Nefkens, B.M.K. ; Pillai, C.T. ; et al.
Nucl.Instrum.Meth.A 271 (1988) 471-474, 1988.

The π − yield in the momentum range 500–740 MeV/ c produced by 800 MeV protons incident on targets of Be and C has been measured at laboratory production angles between 0° and 20°. The yield of 725 MeV/ c π − from Be and C at 0° is a factor of 6 greater than at 20°, for 600 MeV/ c π − the factor is 3. The yield from beryllium is typically 30% higher than from carbon.

TOTAL NEUTRON NUCLEUS CROSS-SECTIONS AT INTERMEDIATE-ENERGIES

Franz, J. ; Grotz, H.P. ; Lehmann, L. ; et al.
Nucl.Phys.A 490 (1988) 667-688, 1988.
Inspire Record 263460 DOI 10.17182/hepdata.37108

Total neutron cross sections have been measured for the nuclei Be, C, O, Al, V, Mn, Co, Cu, Ag, Ce, Ta, Pb, Bi and U at 22 energies from 160 MeV to 575 MeV by the transmission method. The energy region contains the threshold for pion production. Different parametrizations of the experimental results are discussed. A test of charge symmetry was obtained from the proton- and neutron-induced cross sections on C and O, yielding 〈 (σ p − σ n ) σ p 〉 = 0.0012 ± 0.0059 .

LOW-ENERGY PION YIELD AT HIGH-ENERGY ACCELERATORS AS A FUNCTION OF THE PRIMARY PROTON BEAM MOMENTUM

Bertin, A. ; Bruschi, M. ; Capponi, M. ; et al.
Nuovo Cim.A 100 (1988) 305-308, 1988.
Inspire Record 270462 DOI 10.17182/hepdata.37844

High yields of low-momentum pions were obtained from high-energy primary proton beams. The results are discussed, also with respect to the possibility of setting up cloud muon beams from the very lowmomentum poins produced by 10 GeV/c protons.

Charged Particle Multiplicities and Interaction Cross-sections in High-energy Nuclear Collisions

The NA35 collaboration Bamberger, A. ; Bangert, D. ; Bartke, J. ; et al.
Phys.Lett.B 205 (1988) 583-589, 1988.
Inspire Record 262284 DOI 10.17182/hepdata.42035

Inelastic cross sections at 60 and 200 GeV/nucleon are determined in a streamer chamber for 16 O on several nuclear targets. Charged particle multiplicity distributions for inelastic and central collisions are studied and compared with theoretical predictions. The inelastic cross section exhibit a geometrical dependence on nuclear radii. The multiplicity data are governed by the collision geometry. They are consistent with a picture of superposition of independent nucleon-nucleus interactions.

A PRECISION MEASUREMENT OF POLARIZATION PARAMETERS FOR THE PI+ + P ---> K+ + SIGMA+ REACTION AT 13 LABORATORY MOMENTA BETWEEN 1490-MEV/C AND 2069-MEV/C

Haba, J. ; Homma, T. ; Kawai, H. ; et al.
Nucl.Phys.B 299 (1988) 627-639, 1988.
Inspire Record 269585 DOI 10.17182/hepdata.33363

The polarization parameters for the π + +p→K + +∑ + reaction have been measured at 13 laboratory momenta between 1490 and 2069 MeV/ c in the angular range of −0.1⩽ cos θ K ∗ ⩽0.7 with higher statistics than previous experiments. In general, the present results agree well with the results at the Rutherford Appleton Laboratory. It is found, however, that there exist small but systematic differences which can be attributed to certain coefficients in Legendre expansions. The physical significance of these differences is discussed.
