Title: Break-up fragments excitation and the freeze-out volume

Abstract

We investigate, in microcanonical multifragmentation models, the influence of the amount of energy dissipated in break-up fragments excitation on freeze-out volume determination. Assuming a limiting temperature that decreases with nuclear mass, we obtain for the Xe+Sn at 32 MeV/nucleon reaction a freeze-out volume that is almost half the one deduced using a constant limiting temperature.

  • The statistical relationships between lake freeze-up/lake ice break-up dates and air temperature means over various time periods are analyzed for 63 lakes in Finland. Mean temperatures for the individual months before the lake event dates are strongly correlated with these dates; significant correlations hold for periods up to five months in length before freeze-up. Regression coefficients depend on location, but are consistent within regions. Latitude and distance from the coast are the most important sources of variation in the regression coefficients. The regression coefficients are used to translate changes in lake freeze-up/break-up dates into estimated changes in air temperature. Inmore » southern Finland a five day change in freeze-up day would represent a 1.1/sup 0/ C change in November temperature of the same sign. A time series of November temperatures estimated from lake freeze-up dates is derived and compared with observations at Helsinki. The spatial pattern of temperature change over time is also examined using the freeze-up dates. Freeze-up/break-up dates provide a useful proxy for air temperature estimates in data-sparse regions of middle--high latitudes and could permit rapid satellite monitoring of climate perturbations.« less
  • The momentum distribution of {sup 10}Be fragments following direct break-up, {sup 11}Be{r_arrow} {sup 10}Be + n, is expected to reflect the momentum distribution of the valence neutron, and via the uncertainty principle, its density distribution in {sup 11}Be. The one neutron break-up of {sup 11}Be is a two body problem and is less complicated than the three body break-up of {sup 11}Li where the neutrons may be emitted simultaneously or sequentially. The authors present measurements of the central 2 percent in momentum of the parallel momentum distribution of {sup 10}Be fragments from the break-up of {sup 11}Be on targets ofmore » Be, Nb, Ta and U. The A1200 Fragment Separator at the NSCL was operated as a dispersion matched spectrometer producing a beam of 63 MeV/nucleon {sup 11}Be and providing a high resolution measure of the parallel momentum distribution of {sup 10}Be fragments following the break-up. A narrow component, similar in width to that measured for the break-up of {sup 11}Li{sup 1}, is observed for the {sup 10}Be fragments. No target dependence is seen.« less
  • Despite wrenching changes to other regulated industries, the electric utility industry's structure has remained more or less stable since the large holding companies were broken up 60 years ago. Indeed, the Public Utility Holding Company Act (PUHCA) of 1935 limited utility investments outside their individual service areas. The electric utility industry is still composed of a large number of small utility companies that plan for and provide vertically integrated monopoly electric services. There are several emerging trends in this setting. This article makes seven predictions of what the electric utility industry will look like in the future. These predictions covermore » retail wheeling, generation, transmission access, competition, etc.« less
