Search for Parity Nonconservation in Atomic Bismuth

Soreide, D.C. ; Roberts, D.E. ; Lindahl, E.G. ; et al.

In a search for optical rotation near the 8755-Å magnetic-dipole absorption line in atomic Bi, our first results set an upper limit F<10−6 on a parity nonconserving amplitude associated with the line. This limit improves upon earlier parity tests in atoms by three orders of magnitude. Further improvement of at least another order of magnitude appears possible by this method which should then provide an exacting test of parity conservation in the neutral weak-current interaction in atoms.

Upper limit on parity nonconserving optical rotation in atomic bismuth

We have searched for optical rotation near the 8757-Å magnetic-dipole absorption line in atomic bismuth vapor. The experiment is sensitive to parity nonconservation in the weak neutral-current interaction between electrons and nucleons in atoms. We find R≡Im(E1M1)=(−0.7±3.2)×10−8, which is considerably smaller than the value R=−2.5×10−7 obtained by central-field calculations for this bismuth line using the Weinberg-Salam theory of neutral currents.

Study of Pion Absorption Mechanisms in He-4 and Other Nuclei

The spectrum and yield of protons produced by 60-, 100-, and 200-MeV π+ and π− beams on targets of He4, C12, Ni62, and Ta181 have been measured at 45° and 90°. A distinct high-energy component is seen in the protons from He4, which is consistent with a two-body absorption mechanism. Its cross section at 220 MeV is somewhat larger than calculated from the π+ + D process. Possible evidence is also seen for multinucleon absorption modes. The data on heavier nuclei are consistent with earlier experiments.

Measurement of Parity Nonconservation in Atomic Bismuth

Phys.Rev.Lett. 46 (1981) 643-646, 1981.
Inspire Record 942914 DOI 10.17182/hepdata.20642

Parity-nonconserving optical rotation has been observed and measured on the 8757-ÅA magnetic-dipole absorption line in atomic bismuth vapor. The result, R≡Im(E1M1)=(−10.4±1.7)×10−8, is of the approximate size calculated with use of the Weinberg-Salam theory of the weak neutral-current interaction with sin2θW=0.23.

CHARGED PARTICLE MULTIPLICITIES IN PI-, K- AND ANTI-P INTERACTIONS WITH NUCLEI AT 40-GEV/C

Interactions of 40 GeV/c πp-,K− and\(\bar p\) on Li, C, S, Cu, CsI and Pb were studied with the RISK-streamer chamber spectrometer. We present multiplicities of negatively charged particles, as well as of protons, and the correlations between them. The normalized mean multiplicity of negative particles,R−, depends on\(\bar v\), the average number of inelastic collisions as\(R^ -= (0.73 \pm 0.04) + (0.34 \pm 0.02)\bar v\). The dependence of the normalized dispersion of negative particles,D−/<N−>, on the number of protons favours independent collision models and contradicts the coherent tube picture. The excess of fast positive particles behaves asA0.4 and shows, for the heavier nuclei, a clear correlation with identified protons.
