[Q] In 1928 you get your doctorate, and the honors.

Yes, in spring of 1930.

[Q] And in 1928 the doctorate is with what honors?

Summa cum laude.

[Q] With Wien being one of the examiners and he's very happy about your experimental knowledge.

Experimental knowledge, not about my experimental performance. But I knew about cosmic rays and he liked that.

[Q] And, for the Habilitationschrift, who decides that it's okay?

At that time you write your paper, the decision is actually just of your... by your professor, Sommerfeld, but formally you give a lecture to a whole group of faculty members and they... formally they decide that you're satisfactory.

[Q] And then you're officially made a Privatdozent, which gives you the right to teach at any German university.

Correct.
