The general expression for the Amplification $(\\Gamma_{\\perp}/\\Gamma_0)$ was obtained in the region $ql >> 1$ for the energy dispersion $\\varepsilon(\\vec{p})$ near the Fermi point. For various parameters of the quantized wave vector ($\\beta$), the analysis of $\\Gamma_{\\perp}/\\Gamma_0$ against the sub-bands index $(p_i)$; width of AGNR; and magnetic strength $(\\Omega\\tau)$, were numerically analyzed.
