Abstract : We make a systematic analysis of the experimental nuclear stopping power determination. We show that the experimental values are divided into two groups : 1 One of them corresponds to measurements made using a narrow acceptance angle of the detection system along the beam axis. These measurements lead to the evaluation of the mean velocity of an ion beam leaving the target, 2 The other one is obtained by summing the contribution of all the particles scattered in the target. These values give the total nuclear energy dissipated in the target. We give two simple analytical relations to fit these two groups of data.

Keywords : energy loss of particles ion beams
