A search for diffuse neutrinos with energies in excess of 105 GeV is conducted with AMANDA-II data recorded between 2000 and 2002. Above 107 GeV, the Earth is essentially opaque to neutrinos. This fact, combined with the limited overburden of the AMANDA-II ...
IceCube is a km-scale neutrino observatory under construction at the South Pole with sensors both in the deep ice (InIce) and on the surface (IceTop). The sensors, called Digital Optical Modules (DOMs). detect, digitize and timestamp the signals from optic ...
The photochem. of colloidal ZnS was studied under a variety of exptl. conditions. The time dependence of the photocorrosion was examd. by using time-resolved fluorescence, static fluorescence, and electrospectroscopy for chem. anal. (ESCA) techniques. A qu ...
A comprehensive description is presented of the effects on two-spin coherences (i.e., superpositions of zero- and double-quantum coherences) of cross-correlation between the fluctuations of two different relaxation mechanisms in NMR (NMR). Dipole-dipole (D ...
The IceCube observatory is currently being contructed at the South Pole. Scheduled to be completed in 2011, it already offers a large increase in sensitivity over its predecessor, the AMANDA detector. This increase is expected to improve significantly the ...
The rising part of the current waveform observed when discharging an electrostatically charged person or test generator shows some phenomena which have not been explained satisfactorily. This paper describes an attempt to understand these effects using bot ...
The AMANDA-II detector, operating since 2000 in the deep ice at the geographic South Pole, has accumulated a large sample of atmospheric muon neutrinos in the 100 GeV to 10 TeV energy range. The zenith angle and energy distribution of these events can be u ...
