Stable nuclide

  1. May 11, 2009 #1
    Is it possible to combine two more stable nuclides to form unstable nuclides?
    like for example combine Xe and Sr and form U
    In fission it is like

    U + n -> Xe + Sr + n

    can we reverse this process? if one doesnt care about the cost effectiveness

    Well if one looks at the production of superheavy elements, then yes, it is possible to combine two stable nuclides to form an unstable nucleus.

    Transuranics are produced as a by-product of neutron capture in fission reactors. A commerical reactor produces a fair amount of Pu, Am, Cm isotopes. Higher order isotopes have very short half-lives, so they tend not to accumulate.


    209Pb + 54Cr → 262Bh + 1n

    208Bi + 58Fe → 265Hs + 1n

    209Bi + 58Fe → 266Mt + 1n

    208Pb + 62Ni → 269Ds + 1n

    Wow I didnt expect such a detailed feedback
    thank you so much!!
