# Transition from Classical into Quantum Theory for Calculating the Stopping Power of Charged Particles

### Abstract

In this search, we described the most important corrections to standard energy loss formula of charged particles and discussed this formalism with a few remarks by the implication of the inverse – Bloch correction to the stopping power calculations. The inverse Bloch correction extends the range of validity of classical Bohr and quantum Bethe regime. Bohr model operates with a charged particles penetrating in matter as a number of interactions with a harmonically bound classical target electrons but in Bethe theory, all the calculations of energy loss of fast charged particles are based on the first Born approximation which the entire physical system is considered quantized. All the results are got by programming the equations in matlab program.### References
