l. The required field is homogeneous within the desired region and decreases in magnitude to
zero as rapidly as possible outside that region. The magnitude of the ﬁeld is B = E/vo. The
best design is an electromagnet with ﬂat, parallel pole face

. The ﬁrst two electrons are in the ls subshell and have I? = O, with 7718 = i1/2. The third
electron is in the 2s subshell and has 3 = 0, with either ms = 1/2 or —1/2. With four particles
there are six possible interact

1. With more than one electron we are almost forced into some kind of Bohr—like orbits. This
was the dilemma faced by physicists in the early 20th Century.
2. Non‘relativistically K = émv2 and

* 1. Starting with Equation (7.7), let the electron move in a circle of radius a in the xy-plane, so
sin0 = 1. With both 7' and 0 constant, R and f are also constant. Let R = f = 1. Then

1. The function’s output does not approach Zero in the limits ~00 and +00, so it cannot be
normalized over these limits.
