In terms of energy levels, the upper excited states are usually more closely spaced than the energy gap between the lowest excited state (a singlet or triplet) and the ground state. As a result of ...

If an electron is in an excited state it can return to a lower energy level. When it does this, it loses energy. The amount of energy it loses will be equal to the difference in the energy levels ...

Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so ...

These energy levels are influenced by their surrounding environment ... Similarly the resolution is dependent upon the lifetime of the excited state. These two factors limit the number of isotopes ...

This caused the electron to move to a higher-energy level, leaving a "hole" in the lower-energy level. This pairing of one excited electron ... a spin-entangled state with the localized spins ...

Tantalum is one of the rarest elements and has multiple stable isotopes. The least abundant tantalum isotope, Ta-180 is found naturally in a long-lived excited state, a feature unique to this isotope.

elevating its energy level. And when the excited luciferin drops back to its normal state, it releases that energy in the form of light, creating the "fire" in fireflies. It's a remarkable ...

From the start, energy levels in the tightly packed room were high. “Look at this crowd. Do you feel the energy? Do you feel ...

THAT STATE HAS SIX ELECTORAL VOTES UP FOR GRABS ... IT’S SAFE TO SAY THE VOTING MACHINES HAVE BEEN WORKING HARD. ENERGY LEVEL IS HIGH. TURNOUT IS LIKE RECORD TURNOUT. YOU KNOW, SO DURING ...

The timing of the storm should provide a great show for Europe, but those in North America could also see the dazzling lights if the storm persists into nighttime.

After many starts and stops, his company was able to deliver the highest level ... of the state.” Since the homes are designed to create more power than they consume, the excess energy is ...
