    Total reaction cross sections from 141^{141}141Pr(α\alpha,α\alpha)141^{141}Pr elastic scattering and α\alpha-induced reaction cross sections at low energies

    Full text link
    Elastic scattering data for 141^{141}Pr(α\alpha,α\alpha)141^{141}Pr have been analyzed to derive a new energy-dependent local potential for the 141^{141}Pr-α\alpha system. This potential is used successfully to predict the cross section of the 141^{141}Pr(α\alpha,n)144^{144}Pm reaction at low energies where new experimental data have become available very recently. Contrary to various global potentials, this new potential is able to reproduce simultaneously elastic scattering data around and above the Coulomb barrier and reaction data below the Coulomb barrier for the 141^{141}Pr-α\alpha system. Reasons for the partial failure of the global potentials are explained by intrinsic properties of the scattering matrix and their variation with energy. The new local potential may become the basis for the construction of a new global α\alpha-nucleus potential.Comment: 12 pages, 8 figures, Phys. Rev. C, accepte

    The Effects of Clumping and Substructure on ICM Mass Measurements

    We examine an ensemble of 48 simulated clusters to determine the effects of small-scale density fluctuations and large-scale substructure on X-ray measurements of the intracluster medium (ICM) mass. We measure RMS density fluctuations in the ICM which can be characterized by a mean mass-weighted clumping factor C = /^2 between 1.3 and 1.4 within a density contrast of 500 times the critical density. These fluctuations arise from the cluster history of accretion shocks and major mergers, and their presence enhances the cluster's luminosity relative to the smooth case. We expect, therefore, that ICM mass measurements utilizing models which assume uniform density at a given radius carry a bias of order sqrt(C) = 1.16. We verify this result by performing ICM mass measurements on X-ray images of the simulations and finding the expected level of bias. The varied cluster morphologies in our ensemble also allow us to investigate the effects of departures from spherical symmetry on our measurements. We find that the presence of large-scale substructure does not further bias the resulting gas mass unless it is pronounced enough to produce a second peak in the image of at least 1% the maximum surface brightness. We analyze the subset of images with no secondary peaks and find a bias of 9% and a Gaussian random error of 4% in the derived mass.Comment: To appear in ApJ

    Lamb Shift of 3P and 4P states and the determination of α\alpha

    Get PDF
    The fine structure interval of P states in hydrogenlike systems can be determined theoretically with high precision, because the energy levels of P states are only slightly influenced by the structure of the nucleus. Therefore a measurement of the fine structure may serve as an excellent test of QED in bound systems or alternatively as a means of determining the fine structure constant α\alpha with very high precision. In this paper an improved analytic calculation of higher-order binding corrections to the one-loop self energy of 3P and 4P states in hydrogen-like systems with low nuclear charge number ZZ is presented. A comparison of the analytic results to the extrapolated numerical data for high ZZ ions serves as an independent test of the analytic evaluation. New theoretical values for the Lamb shift of the P states and for the fine structure splittings are given.Comment: 33 pages, LaTeX, 4 tables, 4 figure

    Legal Ethics and \u3cem\u3eA Civil Action\u3c/em\u3e

    Get PDF
    This Article shows how A Civil Action can be used to supplement a course in Professional Responsibility. A Civil Action contains many events that can similarly be used to introduce students to ethical dilemmas they will confront when they enter the profession. These events can breathe life into otherwise dry discussions of acceptable ethical behavior as set out in ethical codes. In accord with the Lessons from Woburn Project\u27s goal to make A Civil Action and its associated materials into a powerful teaching tool, the book\u27s events vividly illustrate the ethical parameters within which a lawyer must operate, ethical parameters that exist regardless of how tired a lawyer may be or how antagonistic the opposing party may act

    “In Light of Real Alternatives”: Negotiations of Fertility and Motherhood in Morocco and Oman

    Full text link
    Many states in the Arab world have undertaken wide-ranging family planning polices in the last two decades in an effort to curb high fertility rates. Oman and Morocco are two such countries, and their policies have had significantly different results. Morocco experienced a swift drop in fertility rates, whereas Oman’s fertility has declined much more slowly over several decades. Many point to the more conservative religious and cultural context of Oman for their high fertility rates, however economics and the state of biomedical health care often present a more compelling argument for the distinct differences between Omani and Moroccan family size. While many explanations exist for inconsistencies in fertility trends, integrating these explanations into a cohesive whole allows us to see women as rational actors who make the best choices for their own context. This paper synthesizes existing literature on religion, culture, medicine and economics with field experience to comprehensively examine the multifaceted fertility decision making process of women and couples in Morocco and Oman
