Renormalization of the one-space dimensional Yukawa model by unitary transformation
(Elsevier, 1971-11)
A unitary transformation is used to renormalize the one-space dimensional Yukawa Model in a box. A momentum cut-off dependent sequence of unitary transformations is constructed such that weak limit matrix elements of the ...
Pion multiplicity and Regge trajectories
(Elsevier, 1971-06-07)
Assuming that the zero multiplicity limit of the Poisson distribution in multiparticle production is relaxed to the non diffractive part of the elastic scattering cross section, we obtain the pion multiplicity expressed ...
Parity nonconservation in the hydrogen atom
(Elsevier, 1975-10-13)
We investigate the possibility of observing parity nonconservation with a metastable hydrogen atom beam, by analyzing two effects which should permit detection of the 2S-2P admixture predicted by the Weinberg model.
Carbonyl formation from isooctane combustion in an internal combustion engine
(Elsevier, 1972-12)
Euclidean nonlinear classical field equations with unique vacuum
(Springer-Verlag, 1978-10)
We study the real, Euclidean, classical field equation 0$$]]> where φ: ℝ d →ℝ is suitably small at infinity. We study existence and regularity assuming that λ≧0, F ∈ C ∞ (ℝ), and aF ( a )≧0∀ a ∈∝. These hypotheses allow ...
Backward np scattering with a polarized target
(Elsevier, 1970-04-27)
We measured the polarization parameter P in neutron-proton elastic scattering near the backward direction, using a polarized proton target. Measurements covered the range of incident neutron momenta from 1.0 to 5.5 GeV/c ...
Neutron total cross sections on protons and nuclei in the 10 to 30 GeV/c momentum range
(Elsevier, 1971-10-04)
We present the results of a recent AGS measurement of the total cross section for neutrons on protons, deuterons and other nuclei in the momentum range 10 to 30 GeV/c. The standard good-geometry transmission technique was ...
On the connectedness structure of the Coulomb S -matrix
(Springer-Verlag, 1974-09)
The forward direction singularity of the non-relativistic Coulomb S -matrix is examined and discussed. The relativistic Coulomb S -matrix to order α is shown to have a similar singularity.
Collective electron states in ZnxFe3-xO4 and CdxFe3-xO4 for 0 [les] x [les] 0.3
(Elsevier, 1977)
57Fe Mossbauer measurements of ZnxFe3-xO4 and CdxFe3-xO4 have been made at 300 K in zero applied field and at 180 K in zero and 55 kG applied fields. The compositional dependence of the isomer shifts, B to A area ratios ...
Classical scattering with long range forces
(Springer-Verlag, 1974-09)
We discuss the classical two-body scattering problem for potentials which decrease at infinity like r −α , 1≧α>0. We prove existence and uniqueness theorems for scattering orbits parametrized by their asymptotic data. Wave ...
