New technique to study superheavy elements

Jul 13, 2020So far, optical spectroscopy ends at nobelium, element 102 in the periodic table. Current techniques are at the limit of what is feasible, explained Laatiaoui. From the next heavier element on, the physicochemical properties change abruptly and impede providing samples in suitable atomic states. Get price

The role of stress in the time

Aug 05, 2009Amorphous silicon inverse opals with a complete photonic band gap have been studied with optical pump-probe spectroscopy. The pump-generated free carriers cause the reflection near the band gap to be lowered for the first few picoseconds due to induced absorption. After ∼ 5 ps, this effect disappears and an unexpected blue spectral shift is seen in the photonic band gap. Get price

Spin Noise Spectroscopy in Rb Vapor

The experiment is essentially a noise-based analog to the popular optical pumping experiment already present in many undergraduate laboratories. In this case, Faraday rotation is used to probe spin fluctuations of a gas of alkali atoms in thermal equilibrium in a small magnetic field.

Optical pumping

Optical pumping is a process in which light is used to raise (or pump) electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction, to pump the active laser medium so as to achieve population inversion.The technique was developed by 1966 Nobel Prize winner Alfred Kastler in the early 1950s.. Optical pumping is also used to cyclically Get price
