Neutrinos for geophysics (Feb 16)
http://physicsweb.org/article/news/9/2/9
A physicist in the US has proposed using a beam of neutrinos to measure
the density of the Earth's core. Walter Winter of the Institute for
Advanced Study in Princeton says that neutrinos could provide
information about the Earth that is not available with other techniques
(arXiv.org/abs/hep-ph/0502097). Although measurements of the seismic
waves produced by earthquakes can be used to reconstruct a profile of
the EarthâEUR(TM)s interior, they provide only indirect information.
