A radioactive nucleus X decays to a nucleus Y with a decay constant lambda_X=0.1s^-1 , Y further decays to a stable nucleus Z with a decay constant lambda_Y=1//30s^-1 . Initially, there are only X nuclei and their number is N _0=10^20 . Set up the rate equations for the populations of X, Y and Z. The population of Y nucleus as a function of time is given by N_Y(t)={N _0lambda_X//(lambda_X-lambda_Y)}[exp(-lambda_Yt)-exp(-lambda_Xt)] . Find the time at which N_Y is maximum and determine the population X and Z at that instant.
