ABSTRACT
A continuous energy loss measurements of 63Cu, 28Si, 27AI, 24Mg, 19F, 160 and 12C ions over an
energy range of(O.OG-0.65) MeV/nucleon through thin polymeric foils (Mylar, Polypropylene and
Formvar) were carried out by time of flight spectrometry. The deduced experimental stopping data
have been used in order to assess our proposed semi empirical formula. The proposed approach based
on the Firsov and Lindhard-Scharff stopping power models is provided for well describing-the
electronic stopping power of heavy ions (3 Z < 100) in various solids targets at low energy range.
The '· factor, which was
approximated to be z:i6 , involved in Lindhard, Scharff and Schiott (LSS) formula has been
suitably
modified in the light of the available experimental stopping power data. The calculated stopping
power values after incorporating, effective charge z; of moving heavy ions with low velocities ( v
v0z 13 ) and modified C. in LSS formula, have been found to be in close agreement with measured
values in various solids targets. A reason of energy loss measurements is to obtain
data that help to assess our
understanding of the stopping power theories. For this, the obtained results are compared with, LSS
calculations, MSTAR and SRIM-2013 predictions code.
