• bachelor's degree in 1908
• licentiate degree in 1910
Cont.Cont.
• 1923 until 1937- • position for professor of
physics at University, Uppsala
• Siegbahn married Karin Högbom in 1914.
• two sons: Bo Siegbahn & KaiM. Siegbahn
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
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
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
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.
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
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
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
