1. This theory accounts for and conserves particle energy and angular momentum. 2. It conserves the particle energy and thus is called elastic scattering. 3. :Larger diameter can achieve greater particle energies for the same amount of input energy. 4. In all of those methods, the measured energy is proportional to the initial particle energy . 5. A surprising system of intersecting Cherenkov rings in a biaxial crystal at precisely defined particle energies was predicted. 6. So is there a continuous range of cosmic-ray particle energies , or is there a gap in the range? 7. They are identified by their curvature in a magnetic field and particle energy is measured in a calorimeter. 8. Direct conversion of particle energy to thrust is theoretically simpler, merely requiring magnetically directing a neutral plasma beam. 9. As the particles do not interact, the total energy of the system is the sum of the single-particle energies . 10. He reports particle energies up to about 100 keV, which isn't really'atom-smashing'territory, but is definitely solid proof of principle.
