  nuclear energy loss
     The yield of the secondary ions of hydrogen decreases with increasing energy of Si_(2) clusters and the enhancement of nuclear energy loss of cluster constituents at the surface of sample plays a more significant role in the secondary ion emission of hydrogen at the low energies.

  nuclear energy loss
Furthermore the data are consistent with about 100% contribution of the nuclear energy loss to the CR39 response.
      
Attention is drawn to the large uncertainty in nuclear energy loss at energies >amp;gt; 1000 GeV and the difficulty, as a result of this, in deducing the spectrum from intensity measurements deep underground.
      
Nuclear energy loss models are discussed to introduce an approximation formula for the nuclear stopping cross section appropriate for Thomas-Fermi, Lenz-Jensen and intermediate type potentials.
      
Presuming electronic energy loss (Se>amp;gt;Sn, Sn being nuclear energy loss) to be the dominant phenomenon, they were irradiated by 80-MeV energetic oxygen ions with fluence of 1011 to 1013 ions/cm2.
      
It is well known that the amount of mixing at the interface is proportional to the nuclear energy loss resulting from the elastic collisions.
      
  nuclear stopping power
A simple universal fit formula to experimental nuclear stopping power data
      
Recent experimental data was fitted by using a simple universal relation between nuclear stopping power and particle energy in the range of about 10-4≦?≦102.
      
We find that perturbative treatments with respect to two-body processes do not yield reliable results in the energy regime investigated and that the nuclear stopping power sensitively depends on the order of the two-body correlations considered.
      
However, with decreasing energy the experimental values drop steadily below the theoretical values and near Ed = 18 keV they drop sharply (within 1 keV) reaching the domain of nuclear stopping power.
      
The average rapidity shift of the leading baryon (nuclear stopping power) is studied as a function of the degree of centrality of the collision and the cross-section of the selected events is given.

In this work, the theory of two--bodycollision, thermal spike model and electronic excitation model were used to calculateand analyze the experimental results. It was found that these theoretical calculationsfitted well with the experimental data.
