Half life of lead 208

  1. Jan 13, 2010 #1
    1. The problem statement, all variables and given/known data
    Calculate the half life for alpha decay of [tex] ^{208}_{82}Pb[/tex] (in years)

    2. Relevant equations
    gamow factor
    transmission probability
    coloumb potential

    3. The attempt at a solution

    where r = [tex]1.2(4^{1/3}+204^{1/3}) = 8.969fm[/tex]



    Is it supposed to be worked out in radians? because then the answer i get is 180.427 although this doesn't seem to give a right answer for the half life either

    Is the gamow factor calculation correct?
