WebSection Summary. Half-life t1/2 is the time in which there is a 50% chance that a nucleus will decay. The number of nuclei N as a function of time is N = N0e−λt , where N0 is the number present at t = 0, and λ is the decay constant, related to the half-life by. λ = 0.693 t … WebMay 3, 2024 · You can calculate the half life t ½ = ln2/L = 0.693/L and compare it with the graphical value. The half-life or decay constant you use depends on how you want to reject the dice, usually either 1/6 per throw or 1/2 per throw. 1/6 will give you a smoother curve and a better fit between experiment and calculation - just like real life where ...
WebTau is the time constant, expressed in the same units as the X axis. It is computed as the reciprocal of K. Half-life is in the time units of the X axis. It is computed as ln(2)/K. Span is the difference between Y0 and Plateau, expressed in the same units as your Y values. The derivative of an exponential decay equals -K*Y. WebFeb 12, 2024 · 2.4: Half-lives.
