Fysikexperiment i forskning och samhälle FYS N11, HT 2008

Sixth lecture

In the lecture we discussed a couple of spectroscopic methods, in particular photoemission spectroscopy and x-ray absorption spectroscopy, how to measure them, what kind of data one gets out, and what kind of information is available from the data. The background theme was the deterioration of the Vasa warship and the scientific investigations of the ongoing chemical processes, and the background reading was the following article:
Sandström et al., Nature 415 (2002) 893.

If you're interested in further reading on the Vasa subject, here a three links:
Gunnar Almkvist, PhD thesis, Sveriges lantbruksuniversitet, Uppsala (2008),
Yvonne Fors, PhD thesis, Stockholms universitet (2008),
Y. Fors and M. Sandström, Chem. Sov. Rev. 35 (2006) 399.

Material from the sixth lecture:

Lecture in Powerpoint format

Seventh lecture

Preparatory work:

Please provide the subject chosen in the sixth lecture (see below). Reading hints are given below, but feel free to look for other sources. You should present "your" methods to the other students using the Powerpoint pages, copies of which were distributed last time. The pages will be available during the lecture. Please make sure you won't need more than five minutes for your presentation/explanation.

Please bring along the material distributed at the end of the sixth lecture. We will need it!

Groups and subjects:

Auger electron spectroscopy (AES) - Ulrika, Daniel
Attard & Barnes, section 2.2, especially pages 43 and 44

Electron energy loss spectroscopy (EELS) - Martin, Anders
Attard & Barnes, pages 81-82 and the introduction of section 2.9

Infrared spectroscopy (IR and Raman) - Tuva, Lene, Ayaz
West, paragraph 3.2.3.1, especially pages 71-72
Attard & Barnes, section 3.9.1


Short summary:

Methodwise, we discussed Auger electron spectroscopy, Electron energy loss spectroscopy, Infrared spectroscopy, Extended absorption fine structure spectroscopy, Ion scattering in different ion energy regimes, as well as (x-ray/electron/neutron) diffraction. In conjunction with the latter we briefly resumed the role of the reciprocal lattice. Furthermore, we looked at a number of different detectors (the Si(Li) detector, the gas proportional detector, the "channeltron", and the multichannel plate) and at electrostatic electron/ion energy analysers.
