12th Class Physics Nuclear Physics And Radioactivity

  • question_answer 28)
    Consider the D-T reaction (deuterium- tritium-fusion) given in eqn : (a) Calculate the energy released in MeV in this reaction from the data : (b) Consider the radius of both deuterium and tritium to be approximately 1-5 fin. What is the kinetic energy needed to overcome the Coulomb repulsion ? To what temperature must the gases be heated to initiate the reaction ?  

    Answer:

    From the equation given in the question, refer to nuclear mass of the element given in the brackets and m^ = mass of neutron. If m represents the atomic mass, then (b) Repulsive potential energy is to be provided to the particles in doing so. K.E. needed = Repulsive potential energy  [distance between particle = 2r]
