It was observed that there was a significant difference between the calculated values and the literature values. Another difference with literature is the increased yield ratio N0/N1 of the reaction channels 11B(p,α0)8Be and 11B(p,α1)8Be with increasing energy. The reason for the discrepancy was attributed to being carbon build-up on the target surface during irradiation. Due to the carbon build-up effect in the energy range studied, effective energy (Eeff) values for the 11B(p, α)2α reaction decreased by about 30 keV.</p></abstract>
