1 Átomo multieletrónico

Considere dos eletrones en un átomo con números cuánticos orbitales l1 = 1 y l2 = 2. Encuentre todos los valoresposibles para los números cuánticos correspondientes al momento angular total J .

2 Eisberg Resnick

Veri�car que la extensión de la eigenfunción para tres partículas del ejemplo 9 − 2 es antisimétrica con respecto aun intercambio de marcas de dos de las partúculas.

3 Spín del eletrón

In 1.927 T.E.phipps and J.B.Taylor of de university of Illinois resported an important experiment similar to theStern-Gerlach experiment but using hydrogen atoms instead of silver. This was done because hydrogen is thesimplest atom, and the separation of the atomic beam in the inhomogeneous magnetic �eld would allow a clearerinterpration. The atomic hydrogen beam was produced in a diacharge tube having a temperature of 668 K. Thehighly collimated beam passed along the x direction through an inhomogeneous �eld (of length 3 cm) having anaverage value of 1.240 T

m along the z direction. If the magnetic moment of the hydrogen atom is I Bohr magneton,what is the separation of de atomic beam.
