1. What we do with SRIM

While performing nuclear physics experiment, the main and super important part is the quality, thickness and quantity of target(s). Using nuclear techniques (alpha transmission) one can measure the thickness of the target, however, in order to choose the desired thickness, we check the recoiled residue (after nuclear reaction process) or compound nucleus can be stopped inside the target or not. This is to record the activity induced in the target.

We calculate the stopping power, ion ranges, desire thickness, and many other interesting calculations.

I am interested to give you the taste of powerful tool to understand the kinematics of ion(s).

The above graph (Figure1) explaining the energy loss of 16O in 159Tb. The important point is, during the calculations we considered the mass thickness of 159Tb (foil form) i.e. mg/cm2. Looking how range of an ion depends in the medium can be check in figure 2.
