4. Summary
The analysis of the elastic scattering of protons from 12C
at energies 17, 30.3, 40, 49.48 and 61.4 Mev was per-
formed within the framework of two approaches: an op-
tical code SPIVAL and single folding potential using
DFPOT code. Both approaches give satisfactory results.
The normalization factor Nr was calculated and found to
be in the range 0.75-0.9. A good agreement in the whole
energy range was found using the two previous discussed
approaches with reliable values for the real and imagi-
nary volume integral JV, JW.
