The low energy cross section for the Be(p,y) B reaction has been measured by detecting the delayed e particles from the 'B beta decay. Detailed discussion is presented of the analysis of the radioactive Be target including the use of two independent methods to determine the Be areal density. The direct capture part of the cross section is subtracted from the total cross section to deduce resonance parameters for the 1+ first excited state in B. The zero-energy astrophysical S factor inferred from the present experiment is compared with previous values. The effect on the Cl solar neutrino capture rate, predicted by the standard solar model, is also discussed.
The simple Single Resident Well (SRW) Model has been used to calculate groundwater movement since Fermilab's inception. A new Concentration Model is proposed which is more realistic and takes advantage of computer modeling that has been developed for the siting of landfills. Site geologic and hydrologic data were given to a consultant who made the migration calculations from an initial concentration that was based upon our knowledge of the radioactivity leached out of the soil. The various components of the new Model are discussed, and numerical examples are given and compared with DOE/EPA limits. 7 This is the amount considered to be drought condition usage in a private well. The sum of all the leached radionuclides in the unprotected region for a given beam line gets transported to one well, where it mixes with the daily volume of water that is consumed by a single resident. See Gollon's TM-816 for further discussion. 8 Using as the limits the points at which the star density decreases to 1 % of its maximum value in the r and z dimensions, the activity in this volume is actually about 93% of the total; 99% in z and 94% in r (see Section 5.3).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
