At the time of Heisenberg's arrival in 1920, Sommerfeld had already been engaged with  one central problem: how to explain the behavior of spectra emitted by atoms. Atoms  stimulated by energy would emit not an entire spectrum of radiation, but only specific  lines corresponding to certain frequencies that were characteristic of whatever element  the atom was. Moreover, x-ray spectroscopy posed two problems that had to be  resolved. First was the problem of the lines splitting into doublets and triplets of lines,  called multiplets. Second was the fact that these multiplets turned into a regular pattern  of lines when the atom was exposed to a magnetic field. This anomaly was known as  the Zeeman effect. Four weeks after Heisenberg's arrival, Sommerfeld invited him to take a look at the  Zeeman effect data. Within a year Heisenberg proposed his atomic core model, which

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
