   The masses of the and are known with much better precision in s (u) than in / , due to the relatively poorly known value of the . In atomic mass unit, the mass of the proton is 1.007 276 466 88(13) while that of the neutron is 1.008 664 915 60(55) . 
   At least 10 years. See . 
   For s; in most common nuclei, neutrons are stable. 
   PDG reports the (Γ). Here the conversion τ =  is given instead. 
   Some controversy exists about this data.
