233 U has a much higher fission efficiency by low-energy (thermal) neutrons, compared e.g. with 235 U. Most uranium chemistry studies were carried out on uranium-238 owing to its long half-life of 4.4 years. Source: Internet
And like in these prior examples of unification, the ToE would probably allow us to confidently define the domain of validity and residual error of low-energy approximations to the full theory. Source: Internet
Americium-241 is also suitable for calibration of gamma-ray spectrometers in the low-energy range, since its spectrum consists of nearly a single peak and negligible Compton continuum (at least three orders of magnitude lower intensity). Source: Internet
A graviton in perturbative string theory is a closed string in a very particular low-energy vibrational state. Source: Internet
And then a whole other reality exists for a very distant observer - a low-energy process that does not give rise to quantum entanglement. Source: Internet
