delta ray

• Término histórico en física que designa un electrón secundario expulsado de un átomo por radiación ionizante; en la física moderna de partículas ha sido en gran medida sustituido por terminología más precisa.

A historical term in physics referring to a secondary electron ejected from an atom by ionizing radiation, now largely replaced by more precise terminology in modern particle physics.

1. Secondary electron in physicsC2formal

   A secondary electron ejected from a material when it is struck by a primary particle, such as an alpha or beta particle.

   rayo delta

   • The experiment measured the energy distribution of delta rays produced by alpha particles.
   • Delta rays can cause additional ionization in the detector material.
   • The physicist explained how delta rays contribute to the total energy loss of the primary particle.
