Abstract
Reaction cross sections for production of 11 radionuclides with emerging interest in SPECT imaging are evaluated. Experimental cross section datasets for 40 possible production routes were compiled, discussed and a selection of sets per reaction was proposed for Pade ' fitting leading to recommended values with uncertainties. Only routes for which at least two independent experimental studies were found, with enough data in overlapping energy regions, were considered for selection and fitting. The results of the compilations and available fits are discussed for reactions leading to interesting SPECT radioisotopes: 44mSc (3 routes), 87mY (5 routes), 87gY (m+) (5 routes), 88Y (1 route), 97Ru (5 routes), 131I (1 route), 155Tb (4 routes), 159Gd (3 routes),167Tm-167mEr (8 routes), 191Os-191mIr (2 routes) and 203Pb (2 routes). Integral production yields, based on the Pade ' fits as recommended data, are calculated. A comparison of experimental sets with TALYS-code calculations (results in TENDL-2019 and TENDL-2021 libraries) is made.
