Energy loss straggling in different polymeric foils for α-particles
Abstract
The energy loss straggling in PEN (C7H5O2), PC (C16H14O3) and LR-115 (C6H9O9N2) polymeric foils, for 5.486 MeV α-particles, has been measured and compared with the corresponding computed values based on the most commonly used theoretical formulations viz. Bohr, Lindhard & Scharff and Bethe-Livingston. The aim of the present study is to test the applicability of these theoretical formulations. The behavior of these formulations with the measured values has been analyzed. Finally, Bethe-Livingston formulation has been modified to make it appropriate for thicker targets.
