Abstract
A very intense 227Pa source was produced in order to study the possible 14C and 15N spontaneous emission from 223Ac. After the irradiation of a hemispherical, highly efficient array of nuclear track detectors, about 350 Carbon events were found leading to a branching ratio with respect to alpha decay B= 3.2 10^-11. Comparison with other 14C emitters allows the study of the influence of even-odd effects on cluster radioactivity.Pubblicazioni consigliate
