... Positronium is a short-lived \atomic" system consisting of an electron bound electrically to a positron. This atom is described in a rst approximation by an equation of the same form as the equation for the hydrogen atom, except that the reduced mass is = me=2 = 0:255MeV. a. Calculate the ionizat ...

Spin The evidence of intrinsic angular momentum or spin and its
... The evidence of intrinsic angular momentum or spin and its associated magnetic moment came through experiments by Stern and Gerlach and works of Goudsmit and Uhlenbeck. The spin is called intrinsic since, unlike orbital angular momentum which is extrinsic, it is carried by point particle in addition ...

... Homework assignments will be handed out once per week and must be turned it one week later, same day. We typically have ten homework assignments per semester. Homework is graded on a scale from 1 (= poor) to 3 (very good or excellent). Midterms will be split into a take home problem and a test in cl ...
