     I say the mass is greater (1-.9998)^-1/2 about times
 9.1095*10^-31 kg.
     You say the product of this times .9999c is what is greater
which implies that the mass as observed in mass spectrometers
Kaufmann's experiemtn is greater.
   Of course you can play semantic games but they are only
sematic games unless you can say where the increased momentum
resides.
   I say it resides inside the charged particle and that the mass
does not increase as the spectrometer says but that the magnetic
interaction in Kaufmann's experiment becomes noticeably non
linear as v approaches c.

   You should look at Kaufmann's experiment FAQ
