Using a potential model with relativistic correction we evaluated the spectrum, le-pton decay widths and radiative transition widths of heavy quarkonium systems.
Using the guantum mechanics method to describe the electronically nonadiabatic transition, the equation of the motion of the nonadiabatic transition probability amplitutes have been derived.
A method is proposed to exactly diagonalize the Hamiltonian of a N-layer quantum dot containing a single electron in each dot in arbitrary magnetic fields.
The results also show that green band emission is due to transition from conduction band to deep acceptor level which result in antiposition defect of OZn.
Bohr proposed that electrons occupied discrete energy levels, or " orbits, " and could transition between them by absorbing or emitting precise amounts of energy as light.
Bombard an ordinary hydrogen atom with microwaves of the right frequency and you will lift it out of its ground state by flipping the spin of its electron.
How can the same sum total of solar orbits, lunar phases, terrestrial rotations, or transitions of a cesium-133 atom remain constant, but feel so different in our minds?
For example, if a cloud of gas is blasted by light from a nearby massive star, the gas in it becomes excited; the electrons in its atoms jump to a higher energy level.
