Brief history of the development of quantum mechanics

Saturday, February 27th, 2010

Karl Patrick S. Casas Any object of higher temperature than its surroundings radiates and loses heat. More radiation is produced if you raise the temperature even higher. Even objects at room temperature glow, but in the form of infrared radiation, which is not detectable by the eye. A black body absorbs all frequencies and emits […]

Total Spin States of a Two Particle System Measured at the Ground State

Friday, February 19th, 2010

Christine Marie Ceblano, Liza Marie Dangkulos, Lutchie Dyan Mendoza and Normie Jean Sajor Spin in particle physics and quantum mechanics is a fundamental characteristic property of elementary particles, composite particles and atomic nuclei. All elementary particles of a given kind have the same spin quantum number which is an important part of a particle’s quantum […]

Radial Wavefunction of a Hydrogen Atom

Tuesday, February 16th, 2010

Gibson T. Maglasang and John Paul Aseniero In this article, we outlined the necessary steps in calculating the radial wavefunctions [eq]R_{nl}[/eq] for the Hydrogen atom. Thus, the radial wavefunctions particularly [eq]R_{30 [/eq], [eq]R_{31 [/eq] and [eq]R_{32 [/eq] are easily obtained  without bothering to normalize it. We use the formula below to find the wavefunction, [eq]R_{nl}=\frac{1}{r}\rho^{l+1}e^{-\rho}\nu(\rho),[/eq] […]
