   The known hyperons and their properties are listed in Table I of the companion lectures on Strange Particles. Most of these hyperons have lifetimes of the order of 10⁻¹⁰ sec, with the exception of the Σ⁰-hyperon whose electromagnetic decay has an exceedingly short lifetime.

   What is particularly noticeable is the steep rise in hyperon populations as the limiting mass is approached.
