Energy-selective neutron imaging for morphological and phase analysis of iron-nickel meteorites

We propose energy-selective neutron imaging as a new and non-destructive method to investigate rare metallic meteorites. It is based on attenuation of a neutron beam of limited spectral distribution in a sample depending on the elemental composition and cr ...

Comparison-Based Learning with Rank Nets

Amin Karbasi

We consider the problem of search through comparisons, where a user is presented with two candidate objects and reveals which is closer to her intended target. We study adaptive strategies for finding the target, that require knowledge of rank relationship ...

Marine isotope stage (MIS) 8 millennial variability stratigraphically identical to MIS 3

Jérôme Chappellaz

We have performed the first ever combined-element stable isotopic measurements of extraterrestrial molecules. Methane from two carbonaceous chondrites, Murchison and Cold Bokkeveld, was measured for its hydrogen and carbon isotopic compositions. The combin ...

Photodissociation studies of CH3I and CF3I in fluid 4Helium nanodroplets

Andreas Braun

A novel experimental apparatus to study the dynamics of photodissociation and photoionization processes in the interior or at the surface of helium droplets by means of imaging techniques has been designed, built and characterized. This molecular beam mach ...

Scaling analysis of meteorite shower mass distributions

Anders Meibom

Meteorite showers are the remains of extraterrestrial objects which are captivated by the gravitational field of the Earth. We have analyzed the mass distribution of fragments from 16 meteorite showers for scaling. The distributions exhibit distinct scalin ...
