In this work the energy dependences of the Gompertz type sigmoidal dechanneling function parameters for protons in LT 1 0 0 GT , LT 1 1 0 GT and LT 1 1 1 GT Si crystal channels is investigated theoretically. The proton energy range considered is between I and 10 MeV. The original dechanneling functions are generated using a realistic Monte Carlo computer simulation code. We show that the Gompertz type dechanneling function, having two parameters, I-c and k, representing the dechanneling range and rate, respectively, approximate accurately the original dechanneling function. It is also shown that the energy dependences of parameters I-c and k can be approximated by a linear function and a sum of two exponential functions, respectively. The results obtained can be used for accurate reproduction of experimental proton channeling spectra recorded in the backscattering geometry.
