3. Cont. Born in: Örebro, Sweden, on December 3, 1886 Parents: Nils Reinhold Georg Siegbahn, Emma Sofia Mathilda Zetterberg. bachelor's degree in 1908 licentiate degree in 1910

4. Cont. 1923 until 1937- position for professor of physics at University, Uppsala Siegbahn married Karin Högbom in 1914. two sons: Bo Siegbahn & KaiM. Siegbahn

5. Cont. won the Nobel Prize in physics X-ray spectroscopy 1924 X rays-to determine energies that bind electrons to atoms 1950s turned his attention to electron spectroscopy

6. Facts about X- Rays Wavelength of approx. 10nm to 0.001nm X-ray detectors collect photons of X-ray light X-rays were first reckindised in 1895 X-rays can't travel through metal

7. X-Ray at Hospital X-ray sensitive film on 1 side of body X-rays are shot through you Make you wear a coat jacket Look at Broken Bones

8. X-Rays at the Dentist film in mouth on 1 side of teeth X-rays are shot through jaw just like a picture Does not hurt can't feel X-rays.

9. Nobel Prize 1913 began series of experiments led discoveries of M series of X rays demonstrated the shell arrangement of electrons within atom developed equipment, techniques that established X-ray spectroscopy

10. Cont. awarded 1924 Nobel Prize for Physics later served (1937–64) director of Nobel Institute of Physics in Stockholm Won it for X-ray spectroscopy

11. X-ray spectroscopy basic applications of X-ray analysis: Diffraction X-rays on crystalline to obtain crystal structure Measurement of energy emitted X- rays during SEM imaging X-rays knock out electrons to provide surface chemical
