Target foils of O123800100011 thickness 11.25-mg/cm**2 were cut into pieces of 15-mm*O123800100012 15-mm and glued with zapon onto identical aluminum O123800100013 holders with concentric holes of 10-mm diameter at O123800100014 their centers. Samples for irradiated were taken in theO123800100015 form of a stack of these targets. Aluminum target O123800100016 holders were used for rapid heat dissipation. In order O123800100017 to achieve the desired variation in incident energy, O123800100018 aluminum foils of thickness 6.75-mg/cm**2 were O123800100019 sandwiched between successive target samples of the O123800100020 stack as energy degraders.

Our measured values are in general lower O123800300008 by a factor 2-2.5 than the values of Michel+, O123800300009 especially at higher projectile energies. O123800300010 Mukherjee+ values are lower by a factor of ten than ourO123800300011 values at low projectile energies, while at a O123800300012 projectile energy of 32 MeV and above their values are O123800300013 higher by a factor of about two. O123800300014 Rao+ measurements are higher by a factor of 1.5 - 2 in O123800300015 the higher energy region. O123800300016 HISTORY (20201021A) SD: SF3=N+A -> X in REACTION code.

It is noticeable that below 34 MeV, the O123800400009 measurements of Mukherjee+ are a little lower than our O123800400010 measurements. The cross-sections reported by Rao+ and O123800400011 Michel+ are generally in agreement with ours, between O123800400012 34 MeV and 44 MeV, while above 44 MeV they are higher O123800400013 than ours. Moreover, below 34 MeV the results O123800400014 of Michel+ and Rao+ are exceptionally low by an order O123800400015 of magnitude.
