Abstract
A 4π-β detector was used at the Lohengrin mass separator to measure theβ-activity of mass chains 91, 93, 94, 95, 137 and 139 produced in the thermal neutron induced fission of235U. This activity was analysed intoZ-yields. The different possible corrections were considered and applied to the data. TheZ-yields from this work are compared with the diverse existing results obtained with other methods. The need for and significance of this method to determine theZ-distribution of fission fragments of the heavy group is discussed.
