WebIn alpha decay, a nucleus emits a particle consisting two proton and two neutrons, a helium-4 nucleus. Since the nucleus loses four nucleons total, including two protons, … WebSo the opening angle needs to be chosen based on the lighting purpose. A halogen spot with a 30° opening angle does not radiate the same light as a 30° LED spot light, which is illustrated in the picture above.
