Abstract
The results of the measurement of the energy straggling of low energy alpha particles in the polyatomic and diatomic molecule media are repo rted. A general analytical formula for straggling widths of light ions , obtained by solving Symon's equation for the second and third order central moments of the straggling distributions in non-relativistic ap proximation, has shown remarkably good agreement with experimental dat a at energy losses less than 70% of the initial projectile energies.
