Preliminary results with 'Cincinnati group cell' on thorium 'transmutation' under 50 Hz AC excitation

摘要

The Authors give the procedure and the results of experiments performed with a standard (sup C)incinnati Group Cell(sup ,) aimed to observe possible 'transmutation' of Th in other elements via an Ac electrolytic process. Three techniques have been used to avoid bias due to spurious effects: (alpha)- radiometry, Icp/Ms and Icp/optical, looking at difference between initial and final solution and between blank (no Th) processed solutions. The Authors found deficit of Th after process and new elements produced. The results are still not conclusive on transmutation and the Authors discuss arguments in favour and against the transmutation hypothesis. The Authors clarify the critical points of the measurement techniques, adding some suggestions to improve the reliability of results in future measurements.
