    Formulation of few-body equations without partial waves (1993)
    Springer

    Notes: Abstract A formalism is developed whereby the two-body Lippmann-Schwinger equation may be solved in momentum space without partial-wave decomposition. The integral equation derived is two-dimensional and so is amenable to direct numerical solution. Because the technique uses the well-known helicity formalism, the matrices involved can be further reduced by taking advantage of symmetries common in nuclear and atomic systems (parity conservation, particle symmetry). An example is shown for nucleon-nucleon scattering, and the results are compared to those obtained from the usual partial-wave method.

    Condensed matter effects in the solar neutrino problem (1994)

    Notes: Abstract In addition to our earlier corrections to fusion cross sections, we proposed that previously overlooked condensed matter effects (CME) can help to account for the missing solar neutrino flux. There are three important CME. One is due to a reduction in collision frequency due to an exchange of kinetic and potential energies in collision processes. Another is an excluded volume effect. The third is a shadowing effect due to the presence of spectator species which do not participate in fusion. These CME become appreciable in the high densities encountered in stellar media where they significantly affect fusion rates, since the solar core plasma cannot accurately be described as a collisionless ideal gas. Contrary to Bahcall and Gould (1993), we do not violate Liouville's theorem, the Maxwellian distribution, nor thermodynamics in our proposed solution to the solar neutrino problem.

    Critical review of theoretical models for anomalous effects in deuterated metals (1994)
    Springer
    International journal of theoretical physics 33 (1994), S. 617-670 
    Details

    Topics: Physics
    Notes: Abstract We briefly summarize the reported anomalous effects in deuterated metals at ambient temperature commonly known as “cold fusion” (CF) with an emphasis on the latest experiments, as well as the theoretical basis for the opposition to interpreting them as cold fusion. Then we critically examine more than 25 theoretical models for CF, including unusual nuclear and exotic chemical hypotheses. We conclude that they do not explain the data.

    Conventional nuclear physics solution of the solar neutrino problem (1993)
    Springer

    Notes: Abstract A basic and inherently simple alternative explanation of the solar neutrino problem is proposed based upon conventional nuclear physics. Our results for the tunneling factor, astrophysicalS-factor, and our resolution are compared with rather speculative solutions commonly attempted by accepting the customary ingredients of the standard solar model. We present a more realistic solution of nuclear Coulomb barrier tunneling together with a more precise parametric representation of the astrophysical functionS. We determineS from high-energy (〉100 keV)7Be(p, γ)8B experimental cross-section data using the new tunneling factor. This leads to a low-energy fusion cross section that is lower than previous estimates by ∼26–36%, decreasing the anticipated neutrino flux close to experimentally detected values. This may resolve the missing solar neutrino flux problem.

    Condensed matter effects on nuclear fusion rates in laboratory and astrophysical environments (1993)

    Notes: Abstract Previously overlooked condensed matter effects (CME) can significantly influence nuclear fusion rates in both laboratory and astrophysical environments. In dense plasmas, the ensemble of fusing particles has a significant exchange of kinetic and potential energies. Thus, there are diminished effective flux velocities resulting in a significant selective reduction of fusion rates. Our CME predictions are testable in laboratory experiments and have broad-ranging implications on the fusion rates for stellar media in general. By calculating reaction rates forp(p, e + v e ) D and7Be(p, γ)8B in the sun, we show that CME help to solve the solar neutrino problem.

    Evaluation of effectiveness of a facet wiring technique: Anin vitro biomechanical investigation (1989)

    Notes: Abstract The effects of facet wiring procedure commonly used for stabilizing cervical spines after laminectomy or bilateral facet dislocation on the motion behavior of whole cervical spines are investigated using a Selspot II® system. A fresh human ligamentous intact specimen was potted at T1/T2 vertebra and clinically relevant loads applied to the topmost vertebra (C2) of the specimen. The resulting three rotational components of each of the five vertebral bodies (C3-C7) were recorded. Specimen was injured to mimic total laminectomies at C5 and C6 vertebral levels and tested again. The injured specimen was stabilized, using a facet wiring construct, across C4-C7 segment before testing for the final time. The injured specimens, compared to the intact specimens, demonstrated an increase in flexion-extension of about 10%. Facet wiring imparted stability to the cervical spine by stiffening segments up to roughly four times intact values.
