Low Momentum K+ d Scattering

Glasser, R.G. ; Snow, G.A. ; Trevvett, D. ; et al.

Phys.Rev.D 15 (1977) 1200-1214, 1977.

Inspire Record 124116 DOI 10.17182/hepdata.24651

The differential cross sections for K+d coherent, breakup, and charge-exchange scattering have been measured at several momenta in the interval 250-600 MeV/c. The data have been fitted using a partial-wave analysis. Assuming an s-wave description of I=1 scattering and using data from the coherent and charge-exchange channels, a description of I=0 K+−N scattering by a combination of s and p waves in a simple single-scattering impulse model has been attempted. The phase shifts obtained are unique up to the Fermi-Yang ambiguity, which can be removed by using existing polarization results at 600 MeV/c.

Search for parity noncoserving optical rotation in atomic bismuth

Baird, P.E.G ; Brimicombe, S.M. ; Hunt, R.G. ; et al.

Phys.Rev.Lett. 39 (1977) 798-801, 1977.

Inspire Record 128257 DOI 10.17182/hepdata.20929

We report the results of a laser experiment to search for the parity-nonconserving optical rotation in atomic bismuth. We work at wavelengths close to the 648-nm J=32 — J=52 M1 transition from the ground state. We find R=Im(E1M1)=(+2.7±4.7)×10−8, in disagreement with the theoretical value R=−30×10−8 predicted for this transition on the basis of the Weinberg-Salam model of the weak interactions combined with relativistic central-field atomic theory.

Measurement of the Magnetic Structure Function of the Deuteron at q2 = 1.0-(GeV/c)2

Martin, F. ; Arnold, R.G. ; Chertok, B.T. ; et al.

Phys.Rev.Lett. 38 (1977) 1320, 1977.

Inspire Record 109585 DOI 10.17182/hepdata.21023

At a square of the momentum transfer of 1.0 (GeV/c)2 the elastic scattering of electrons on deuterons has been measured at electron scattering angles of 8°, 60°, and 82°. From these data we have extracted a value of B(q2)=(0.59±1.20)×10−5 for the deuteron. This measurements extends the range in momentum transfer by almost a factor of 2 over the previous measurements.

$\pi^- p$ Interactions at 360-GeV/c: Measurement of the Total and Elastic Cross-Sections and the Charged Particle Multiplicity Distribution

Firestone, A. ; Anderson, E.W. ; Chang, V. ; et al.

Phys.Rev.D 14 (1976) 2902, 1976.

Inspire Record 3926 DOI 10.17182/hepdata.24670

In a sample of 108 563 pictures taken with the Fermilab 30-inch hydrogen bubble chamber, exposed to a 360-GeV/c π− beam, we have observed 19 453 interactions in a selected fiducial region. The observed charged multiplicity distribution has been corrected for the effects of scan efficiency, errors in prong count, missed close-in vees, secondary interactions, and neutron stars and for Dalitz pairs. The two-prong events have been corrected for losses at low −t. The total cross section is measured to be 25.25 ± 0.35 mb, and the elastic cross section is 3.61 ± 0.11 mb with an exponential slope of (8.82 ± 0.30) (GeV/c)−2. The average charged-particle multiplicity for inelastic events is 8.73 ± 0.04, and the second moment f2 is measured to be 9.83 ± 0.23.

Properties of Inclusive Hadron Spectra in Muon Nucleon Scattering at 150-GeV/c

Anderson, H.L. ; Bharadwaj, V.K. ; Booth, N.E. ; et al.

Phys.Rev.Lett. 36 (1976) 1422, 1976.

Inspire Record 3759 DOI 10.17182/hepdata.3268

We have studied muon-produced hadrons from a deuterium target. The structure functions and the charge ratios are reported for neutrons; the transverse momentum and azimuthal distributions are reported for deuterons. The structure function for the neutron is similar to that of the proton. The charge ratio of produced hadrons follows the expectation of a simple spin-½ quark model. Transverse-momentum results agree with those at lower energy and are similar to those from hadron-hadron interactions. No azimuthal anisotropy is seen.
