In order to study giant resonance induced by Li scattering, optical model (OM) analysis of Li elastic scattering is necessary to get the optical parameters. OM has been widely used to analyze the heavy ion scattering data in term of empirical Woods-Saxon (W-S) parameterizations of the nuclear potential. However, it was found that a satisfactory microscopic understanding of heavy ion scattering ...

Recent advances in the techniques of atom and ion trapping have opened up a new vista in precision β decay studies due to the near-textbook source they provide: very cold (. 1 mK) and localized (. 1 cm), with an open geometry where the daughter particles escape with negligible distortions to their momenta. Atom traps: Magneto-optical traps (MOTs) have demonstrated the ability to measure the ang...

A review and expansion of the circuit analogy method of modeling and analysing multiconductor TEM mode rf resonators is described. This method was used to predict the performance of the NSCL K500 and K1200 cyclotron resonators and the results compared well to the measured performance. The method is currently being applied as the initial stage of the design process to optimise the performance of...

Measurement of gamma radiation using thermoluminescent dosimeters on three uranium mill tailings areas and a control area showed exposure rates below ground depended on the amount and type of soil covering. Covering tailings with 30 cm of shale and 60 cm of topsoil reduced gamma radiation exposure belowground to rates similar to the control area. Soil covering of 30 cm was adequate to reduce ga...

Understanding the chemistry of carbon nanotubes is a crucial step towards their ultimate practical use. Here we report the Ž . first nanoscale images of single wall nanotubes SWNTs whose sidewalls have been chemically derivatized. Scanning Ž . tunneling microscopy STM images of fluorinated SWNTs reveal a dramatic banded structure which indicates broad continuous regions of fluorination terminat...

The nutria or coypu (Myocastor coypus) is a rodent native to South America that has been introduced almost worldwide since the early 1900’s, originally with the intent of fur farming in many cases. The nutria is a large (over 6 kg), semi-aquatic rodent with a voracious appetite and high reproductive potential. Nutria became established in the Louisiana wetlands in the 1930’s. The habitat proved...
