Abstract

An analysis of widths of resonant states supports the hypothesis that particle lifetimes are quantized in units of $\frac{1}{2}$ or possibly $\frac{1}{4}$ the lifetime of the $ρ$ meson: (4.40 ± 0.06) X $10^{- 24}$ seconds. The probability that the observed regularity in resonance widths (lifetimes) is simply due to chance is estimated to be less than 2 X $10^{- 4}$ . Possible ramifications of this result are considered.
