CE ÎNSEAMNĂ BETA PARTICLE ÎN ENGLEZĂ?
Beta particula
Beta particulele sunt electroni de mare viteză, electroni de mare viteză sau positroni emise de anumite tipuri de nuclee radioactive, cum ar fi potasiul-40. Particulele beta emise sunt o formă de radiații ionizante, de asemenea cunoscute sub numele de raze beta. Producția de particule beta se numește decalaj beta. Acestea sunt desemnate prin scrisoarea greacă beta. Există două forme de dezintegrare beta, β și β +, care dau naștere la electron și positron.
Definiția beta particle în dicționarul Engleză
Definiția particulei beta în dicționar este un electron de mare viteză sau un pozitron emis de un nucleu în timpul dezintegrării radioactive sau a fisiunii nucleare.

Like the alpha particle, the beta particle interacts with matter via (i) ionization and
(ii) electron orbital excitation as it dissipates its kinetic energy. A third mechanism
of interaction with matter, which distinguishes the beta particle, is radiative ...

Beta-particle Interactions with Matter Owing to the very low mass of the beta-
particle (i.e., electron) compared with the alpha particle, it travels at a much
higher velocity than an alpha particle of equivalent energy. Because of its greater
velocity, ...

In beta decay, the change in the binding energy appears as the energy
equivalent mass and kinetic energy of the beta particle, the energy of the
antineutrino or neutrino, and the kinetic energy of the recoiling daughter nucleus.
Because this ...

An alpha particle is equivalent to the nucleus of a helium atom and consists of 2
protons and 2 neutrons. A beta particle is equivalent to an electron. Gamma
