2. Use the simple theory given in class to estimate the -decay half-life of 209Bi(Q=3.13MeV), given the known half-life of 2.1min for the decay of 211Bi(Q=6.749MeV). Assume that the frequency f(fv/2R) and -particle preformation probability P are the same for both isotopes. Use R=1.2(A1/3+41/3) fm for the radius corresponding to the Coulomb barrier. Does your result support the fact that 209Bi is considered stable with a half-life in excess of 1019 years
