THE PRODUCTION OF XE-127 VIA (NAT)XE(P,XN)CS-127-]XE-127

Effective cross-sections for the production of Cs-127 in the bombardment of (nat)Xe with protons were measured from threshold up to 100 MeV. From the integral excitation function obtained, yield curves for Xe-127, produced via the (nat)Xe(p,xn)Cs-127 --> Xe-127 route, were derived for a full range of ps target thicknesses. These curves can be used for the optimization of the production of Xe-127 within specific practical incident energy and target thickness constraints. The expected optimum yield for a representative production gas target (1.64 g/cm2 thick) is 6.7 MBq/muAh (obtained at an incident energy of 39.3 MeV).
