Quantum Mechanics: I
  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
