- Note that a thermal neutron is a neutron whose most probable kinetic energy is ~ 0.025 eV. What is the de Broglie wavelength of a thermal neutron? (Hint: Neutrons in a nuclear reactor are thermalized in order to enhance their probability of fissioning 235U.)According to the article Alien Antimatter Crashes into Earth 2 : More than 60 years ago, future Nobel laureate Sheldon Glashow predicted that if an collided with an antineutrino the antimatter answer to the nearly massless neutrino electron, it could produce a cascade of other particles. The "Glashow resonance - phenomenon is hard to detect, in large part because the antineutrino needs about 1,000 %3D times more energy than what's produced in the most powerful colliders on Earth. Let's compare this event to an ordinary baseball with a mass of 146 g. Please use three significant figures in your calculations.What is the relation between the de Broglie wavelength λ, mass m, and kinetic energy K for (a) a lowenergy proton, and (b) a very high energy proton?
- What is the minimum energy (measured in eV) required to ionize a Hydrogen atom in the level n=r?(3) A gamma-ray photon with an energy of 1 GeV collides with a stationary proton. The photon scatters backwards, opposite the direction it had before the collision. The proton scatters in the direction that the photon had before the collision. (a) What is the energy of the scattered photon? (b) What is the momentum of the scattered photon? (c) What is the kinetic energy of the scattered proton? (d) What is the momentum of the scattered proton? (e) The Sun generates energy because of nuclear reactions that occur in its core. A sequence of reactionsS that do this is called the PP I chain (pronounced "p p one chain"). In the PP I chain, four protons fuse into a helium-4 nucleus and two positrons, since charge is conserved. Also emitted are two neutrinos, since angular momentum is conserved. The neutrinos have no charge and negligible mass. Assume all motion in the PP I chain is non-relativistic, except for the neutrinos. How many MeV of energy does one PP I chain generate? Include the…Compare the wavelength of 1.0-MeV gamma-ray photon with that of a neutron having the same kinetic energy. (for a neutron, mc² = 939 MeV)
