Question
A collimated beam of 7-mesons of 100 MeV energy passes through a liquid hydrogen bubble chamber. The intensity of the beam is found to decrease with distance s along its path as exp(-as) with a = 9.1 × 10¯² m¯¹. Hence calculate the life time of the л-meson (Rest energy of the л-mеson 139 MeV)
