Half life time
WebFeb 20, 2024 · Half-life \(t_{1/2}\) 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 \[N = N_0e^{-\lambda t},\] … WebFeb 16, 2024 · Add a comment. 1. It is just a matter of taste whether you prefer to write an exponential decay with the time constant τ and powers of e. (1) N ( t) = N 0 e − t / τ. or with the half-life t 1 / 2 and powers of 2. (2) N ( t) = N 0 2 − t / t 1 / 2. Both ways are equivalent and you can switch between them by using.
