6.5: Monday 11-12
-----------------
Task 1: There are different approaches to calculate geometrical acceptances (or geometrical factors).
You may compare the approaches of the model solution and the approach in the paper J.D.Sullivan:"Geometrical factor
and directional response of single and multi-element particle telescopes". The resulting integrals can be tricky:
here it is only important to understand the general concept.
Task 2: -
Task 3: The integral in d) follows from a differential equation (to be dealt with in Exercise 5.2)
Task 4: The last decaying proton of the universe: The calculated answer will give the
time for a 50%-50% probability of last proton decay.
