WebAn alpha particle is a kind of particle emitted spontaneously during the type of radioactive decay known as alpha decay. An alpha particle is identical with the nucleus of a helium atom ( 4 He), consisting of two protons and two neutrons. The rest mass of the alpha particle is 6.64424 × 10 -27 kg, or 3.7273 × 10 9 eV. WebIf anyone could help me with this question I would be very thankful. 1) In a radioactive decay of a nucleus a B+ particle is emitted followed by a Y photon of wavelength 8.30x10^-13. a) … arrangotang

WebEassociated with a moving particle of rest mass m 0. It was: E= m 0c2: (1) This result was guessed, and the guess then checked. The guess involved studying the decay of a particle of rest mass M 0 into a lighter particle and a photon. A portion m 0 of its mass is used to create a photon having energy E = m 0c2 and momentum p = E =c= m 0c.
