This is a statistics problem which i need some help with as amu unsure how to answer it.
Particles hitting a detector undergo a collision after an average path length Lo= 10 cm. After the collision, the particle deposits all of its energy in thedetector and is stopped. How thick does the detector need to be so that 99%of the incoming particles are stopped?
I believe that using a poisson distribution may help but tried using the poisson distribution and couldn't get a reasonable answer.
Any help or tips would be appreciated.
