Bremsstrahlung is most likely to occur if a particle is somewhere in the inner electrons of the atom. What is likely to happen when an alpha particle comes close to the end of its path. less ionization because it has lost a lot of energy. more ionization because it is in contact with matter longer.
4 mar 2022 · Charged particles (such as alpha particles and electrons/positrons) going through matter can interact both with the nuclei –via the nuclear interaction and the coulomb interaction– and with the electron cloud –via the Coulomb interaction.
number electrons appeared because of the interactions of the ionization particle with matter is n primary, whereas n total is the number of electrons appearing after interactions of initial electrons with matter.
If a photon enters matter with an energy in excess of 1.022 MeV, it may interact by a process called pair production. The photon, passing near the nucleus of an atom, is subjected to strong field effects from the nucleus and may disappear as a photon and reappear as a positive and negative electron pair.
Interaction of Light and Matter. Atomic or molecular gases in low concentration show sharp energy eigen spectra. This was shown for the hydrogen atom.
