Gibson T. Maglasang and John Paul Aseniero In this article, we outlined the necessary steps in calculating the radial wavefunctions for the Hydrogen atom. Thus, the radial wavefunctions particularly , and are easily obtained  without bothering to normalize it. We use the formula below to find the wavefunction,               [...]

John Paul Aseniero and Gibson T. Maglasang For the particle in the state , the expectation value of x is expressed as where the expectation value is the average of repeated measurements on an ensemble of identically prepared systems. In this article, we would like to find , , and for an electron in the [...]

Eric Alcantara, Carlo Paul Morente and Gibson T. Maglasang If you have two particles of spin and . Let be the combined spin of the particles. You can get values of from down to :                (1) We can get then the combination of states from the total spin [...]
