After becoming step by step acquainted with the ideas of special
relativity, relativistic kinematics and time dilatation, the
user is able to apply these laws to the decay of instable particles.
17- to 18-year old students in advanced physics courses are
led in few hours to measure themselves the mean lifetime of
the K0 particle in the realistic environment of the BaBar experiment
at SLAC, California. The package can be used either by a teacher
for demonstration purposes in a whole class situation, or on
an individual / small group basis.
