The new Surrey ion beam analysis facility

We present the characteristics of an ion beam analysis facility based on a fully computer controlled 2 MV Tandetron commissioned in 2002. The terminal voltage temperature stability is measured using the 3036 keV O(a; a)O resonance. A microbeam beamline with an Oxford triplet lens and a coolable sample holder has been built. We report new temperature dependent time-resolved IBIC measurements fro...

Computer-Aided Chemistry at Surrey — the way ahead

This article describes the objectives and rationale of the degree course in Computer-Aided Chemistry at the University of Surrey. The course, which is the first of its kind, represents a sharp break with the past in that industry was intimately involved in the early stages of the planning as well as providing subsequent support; furthermore, much of the teaching is done via a workshop approach....

Two Exoplanets Discovered at Keck Observatory

We present two exoplanets detected at Keck Observatory. HD 179079 is a G5 subgiant that hosts a hot Neptune planet with M sin i = 27.5 M⊕ in a 14.48 d, low-eccentricity orbit. The stellar reflex velocity induced by this planet has a semiamplitude of K = 6.6 m s. HD 73534 is a G5 subgiant with a Jupiter-like planet of M sin i = 1.1 MJup and K = 16 m s −1 in a nearly circular 4.85 yr orbit. Both ...
