  This is the first Internet course on elementary quantum mechanics written in
Spanish ("castellano") for the benefit of Spanish speaking students. I thank my
eight Mexican students at the Institute of Physics, University of Guanajuato,
Leon, (IFUG), for the collaboration that made this possible. The topics
included refer to the postulates of quantum mechanics, one-dimensional barriers
and wells, angular momentum, WKB method, harmonic oscillator, hydrogen atom,
quantum scattering, and partial waves
