Is 4^2He a gamma radiation

No, 4^2He is not gamma radiation. The notation 4^2He represents an isotope of helium, specifically the isotope helium-4. Gamma radiation, on the other hand, is a high-energy electromagnetic radiation emitted during certain nuclear processes.

No, 4^2He is not gamma radiation. 4^2He represents an isotope of helium, where the superscripts indicate the mass number (the total number of protons and neutrons) and the subscripts represent the atomic number (the number of protons). In this case, 4^2He means there are 4 nucleons (2 protons and 2 neutrons) in the helium nucleus. Gamma radiation, on the other hand, refers to high-energy electromagnetic radiation emitted from the nucleus of an atom during radioactive decay or nuclear reactions.
