Webdecay constant : the probability or chance that an individual nucleus will decay per second. (You may like to comment on the problem with notation in physics. is used for wavelength as well as the decay constant. The context should make it unambiguous.) Units: is measured in s-1 (or h-1, year-1, etc).
WebFor example, free neutrons decay with a half-life of about 10.3 minutes. This corresponds to a decay constant of . 067/min and an average lifetime of 14.8 minutes or 890 seconds and is represented as t avg = 1/ λ or Average life = 1/ Decay Constant. The decay constant is its probability of decay per unit time.
