Abstract :
The spatial distribution of charges, injected by monoenergetic electrons in Teflon FEP have been determined by two different techniques, i.e. laser-induced pressure pulse (LIPP) technique, and laser-intensity modulation method (LIMM). A comparison of the results, provided by the two techniques shows good agreement
