Can an electron traveling near the speed of light knock a proton or neutron out of a nucleus?

The electron and bremsstrahlung photon energies that we are talking about here for nuclear transmutation are in the MeV region, so this energy corresponds to binding energies of nucleons. The deuteron binding (dissociation) energy is about 2.2 MeV, for example. The normal light scattering and "electron excitation and photon re-emission" you mention is an atomic, not nuclear, excitation process.gonegahgah said:Thanks BobS.
It is also the photons I am curious about as well.
I'm trying to get a feel for the intersize particle 'heftiness'.
Electrons have about 1/1836 the mass of of a proton (1/1839 of a neutron).
This makes it harder for electrons to push protons around I imagine than vice-versa; the electrons go where the proton goes; not vice-versa.
When hydrogen fuses to helium the conversion of mass to energy is about 1/142 the mass (a site said 0.7%; that is 1/142 isn't it?).
More mass than that contained in an electron is converted is it? Wow!
But that doesn't correspond to a single photon does it?
Afterall normal light scattering due to 'electron excitation and photon re-emission' doesn't correspond anywhere near that relative quantity of energy.
Interparticle interaction refers to the forces and interactions that occur between particles in a system, such as atoms, molecules, or larger particles. These interactions can include attractive forces, repulsive forces, and electrostatic interactions.
Interparticle interactions play a crucial role in many physical, chemical, and biological processes. They determine the structure, properties, and behavior of materials, and can impact the overall performance of a system. Understanding and controlling interparticle interactions is essential in fields such as materials science, nanotechnology, and biophysics.
Colloidal systems, which consist of small particles dispersed in a medium, are highly influenced by interparticle interactions. These interactions can cause particles to aggregate or repel each other, leading to changes in the stability, rheology, and optical properties of the system. Understanding and controlling interparticle interactions is crucial in the design and development of colloidal systems for various applications.
The strength and type of interparticle interactions are influenced by various factors, including the size, shape, and surface chemistry of the particles, the properties of the surrounding medium, and the distance between particles. The presence of external forces, such as electric or magnetic fields, can also affect interparticle interactions.
There are various experimental techniques and theoretical models used to study and manipulate interparticle interactions. These include microscopy, spectroscopy, scattering techniques, and computer simulations. Manipulating interparticle interactions can be achieved through techniques such as surface modification, controlling the surrounding environment, and using external fields to alter the forces between particles.
