چکیده
In formula (12) the factor Op (y, b) in the exponent should be replaced by l2 op (y , b), corresponding to absorption of the wave amplitude by a factor e -d/z% where d denotes the distance traversed through a medium in which the mean free path is h 3 l/Fp . This hss the effect of doubling the crosssection estimate in Eq. (14) to 66 mb <” Cr pN <” 94 mb. There a;e no other changes. We also wish to refer to estensi-ve studies by Professor Marc Ross and Dr. Leo Stodolsky on this and related nuclear coherence subjects which are in press but of which we were not ;LW~;~ 7.0 lvhen this calculation was done and submitted for publication.

The real part of the virtual Compton amplitude can be directly determined from measurements of electron (or muon) bremsstrahlung or pair photoproduction. In general, the interference of the Compton amplitude with the Bethe-Heitler amplitude for pair production or bremsstrahlung yields a contribution to the cross section which is antisymmetric when the leptons are interchanged. This interference...
متن کاملComplete set of total cross sections for imaginary parts of nd forward scattering amplitudes, and three-nucleon force effects
In neutron-deuteron scattering, four total cross sections are shown to form a complete set for the determination of the imaginary parts of the forward amplitudes by means of the optical theorem. The amplitudes are decomposed into scalar and tensor components in spin space. Contributions of three-nucleon forces ~3NF! to these amplitudes are studied by Faddeev calculations. Significant effects of...
متن کاملTotal Forward and Differential Cross Sections of Neutral D Mesons Produced in 500 GeV / c π − – Nucleon Interactions
We measure the neutral D total forward cross section and the differential cross sections as functions of Feynman-x (xF ) and transverse momentum squared for 500 GeV/c π–nucleon interactions. The results are obtained from 88 990±460 reconstructed neutral D mesons from Fermilab experiment E791 using the decay channels D →K−π+ and D →K−π+π−π+ (and charge conjugates). We extract fit parameters from...

The 5-dimensional spin-0 form of the Kemmer-Duffin-Petiau (KDP) equation is used to calculate scattering observables [elastic differential cross sections (dσ/dΩ), total cross sections (σTot), and reaction cross sections (σReac)] and to deduce σTot and σReac from transmission data for K ++ 6Li, 12C, 28Si, and 40Ca at several momenta in the range 488− 714 MeV/c. Realistic uncertainties are genera...
متن کاملA complete set of total cross sections for imaginary parts of nd forward scattering amplitudes and three-nucleon force effects
In the neutron-deuteron scattering, four total cross sections are shown to form a complete set for the determination of the imaginary parts of the forward amplitudes because of the optical theorem. The amplitudes are decomposed into scalar and tensor ones in the spin space. Contributions of threenucleon forces (3NF) to these amplitudes are studied, by the Faddeev calculation, which predicts sig...
