Single-electron capture in keV Ar15+...18++He collisions (2008)

Knoop, S., Fischer, D., Xue, Y., Zapukhlyak, M., Osborne, C. J., Ergler, T., ...

Single-electron capture in 14 keV q−1 Ar15+...18++He collisions is investigated both experimentally and theoretically. Partial cross sections and projectile scattering angle dependencies have been...

A preliminary model of non-domestic energy use for England and Wales (2006)

Bruhns, H., Steadman, P., Marjanovic, L.

This paper describes an interim but detailed activity based model of energy use in non-domestic premises in England and Wales for the year 2004. Floorspace data from the Valuation Office Agency and...

Air conditioning surveys in the UK retail sector, or 'keeping the cold in' (2006)

Brown, N., Caeiro, A.J., Bruhns, H., Wright, A.J., Summerfield, A.J., Oreszczyn, T.

It is known that airconditioning use in some sectors of the UK's non-domestic building stock, is increasing rapidly and may be approaching saturation, but exact reliable figures are scarce. It is...

Benchmarking high-field few-electron correlation and QED contributions in Hg75+...78+ ions: I. Experiment (2006)

González-Martínez, A. J., Braun, J., Brenner, G., Bruhns, H., Lapierre, A., ...

The photorecombination of highly charged few-electron mercury ions Hg75+ to Hg78+ has been explored with the Heidelberg electron beam ion trap. By monitoring the emitted x rays (65–76 keV) and...

Lifetime measurement of the Ar XIV 1s2 2s2 2p 2P3/2 metastable level at the Heidelberg electron beam ion trap (2006)

Lapierre, A., Braun, J., Brenner, G., Bruhns, H., Fischer, D., ...

We present the details of an accurate lifetime measurement of the 1s22s22p 2P3/2o metastable level in boronlike Ar XIV performed at the Heidelberg electron beam ion trap [A. Lapierre et al., Phys....

Do Electrons and Ions Coexist in an EBIT? (2005)

Lapierre,A., Braun,J., Brenner,G., Bruhns,H., Fischer,D., ...

Detailed analysis of an extended exponential tail observed in the decay curve of the 2P3/2-2P1/2 magnetic dipole (M1) transition in boron-like Ar13+ provides evidence that electrons and ions might...

Life course epidemiology: an alternative approach to the collection and analysis of carbon emission data (2005)

Summerfield, A.J., Bruhns, H., Caeiro, J.A.J., Oreszczyn, T., Steadman, J.P.

Developing policy for the reduction of the carbon emissions due to buildings requires models for energy usage that incorporate social, behavioural, and environmental factors in addition to the...

Novel technique for high-precision Bragg-angle determination in crystal X-ray spectroscopy (2005)

Braun, J., Bruhns, H., Trinczek, M., Ullrich, J.

A novel technique for a high-precision large acceptance determination of the Bragg angle in crystal x-ray spectroscopy is presented and demonstrated. The method exploits visible light beams as...

High precision measurements of forbidden transitions in highly charged ions at the Heidelberg EBIT (2005)

Artemyev, A., Braun, J., Brenner, G., Bruhns, H., Draganic, I. N., ...

Few-electron ions, which can be produced and studied at rest in electron beam ion traps (EBITs) are very well suited for the study of nuclear size effects and QED in strong fields, but the various...
