Estimating the energy released in fission

  1. Jan 13, 2012 #1
    I have been asked in a past exam paper to estimate the energy released by the fission of one 235U nucleus. I am given the mass of a 235U nucleus and also 141Cs nucleus and 93Rb nucleus in the 'Useful constants and formula' section of the exam so I wondered if I had to use these, although obviously 141 and 93 do not sum to 235 so I wondered if there was a method to estimate the energy released by a fission without using mass differences etc, like if you just used an estimate of the energy released per nucleon in fission or something? Many Thanks

    Did the 'Useful constants and formulae' also contain the mass of the neutron? ;)

    Ah yea so do you add the neutron mass to the Rb and Cs nuclei and make this the products and calculate the mass deficit this way?
