The Moment

Using the magnetic environment model, the moment distributions for ferromagnetic COl_xMnx alloys in the composition range (0 < x < 0�25) were calculated from the mean saturating moments of the alloys. The calculation also gives the mean moment of each species as a function of concentration. The predictions correspond extremely well with the existing experimental data. In particular, the increase in the correlation length close to the ferromagnetic critical concentration is clear in the cross section data and model.

The transport coefficients υdr and D⊥/μ have been measured in mixtures of 0.5 % and 4 % hydrogen in argon. All measurements were made at 293 K. It is shown that for these mixtures the use of the solution of the Boltzmann equation based on the two-term Legendre expansion of the velocity distribution function introduces no significant error in the analysis of the transport data. All the experimental data have been predicted to within � 3.5 % using previously published cross section data.

The cross-section for the photodisintegration 12 C( γ , 3 α ) has been determined for γ -ray energies up to about 60 MeV from a study of 2500 stars in nuclear emulsions. The methods used in selecting and identifying the stars are described, and full details are given of the corrections (for escape, observer efficiency, etc.) required for converting the experimental data into cross-section values. The cross-section exhibits at least five resonances, situated at γ -ray energies ( E y ) of 17.3, 18.3, 21.9, 24.3 and 29.4 MeV, and a strong minimum at E y ~20.5 MeV. This behaviour suggests that a well-defined compound nucleus is formed, the minimum near 20.5 MeV resulting from ( γ , n ) and ( γ , p ) competition. Furthermore, the finer details of the cross-section data are consistent with current knowledge of the 12 C level structure. The integrated cross-section is 1.21 ± 0.16 MeV mb for E y < 20.5 MeV, a further 2.8 ± 0.4 MeV mb for 20.5 ≤ E y < 42 MeV, and < 0.2 MeV mb for 42≤ E γ <60 MeV (where the symbol mb denotes 10 -27 cm 2 ). As a subsidiary result of the main work, the existence of the reaction 13 C( γ , n ) 3 α has been established.

The differential cross-section data from the CLAS Collaboration for [Formula: see text] have been analyzed based on an effective Lagrangian approach. The [Formula: see text]-channel [Formula: see text], [Formula: see text], [Formula: see text] exchanges, the [Formula: see text]-channel [Formula: see text] and near-threshold [Formula: see text]’s exchanges, the [Formula: see text]-channel [Formula: see text], [Formula: see text], [Formula: see text] exchanges, and the generalized contact term are considered in constructing the reaction amplitude. It is found that by including the [Formula: see text] resonance, which is responsible for the shape of the angular distribution of [Formula: see text] near the [Formula: see text] threshold, and one of the [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] resonances, one can describe the cross-section data for this reaction reasonably well. More experimental data on spin observables are needed to further pin down the resonance contents and associated resonance parameters in this reaction.

The Empirical Analysis

This paper develops and illustrates the use of two methodologies to analyze the effect of unions on productivity in the public sector. Although the methodologies are applicable to a wide variety of public sector functions, the focus of the paper is on municipal libraries because of the availability of relevant data. The empirical analysis, which uses 1977 cross-section data on 260 libraries, suggests that collective bargaining coverage has not significantly affected productivity in municipal libraries.
