Gamma-gamma coincidences and electron conversion measurement in141La

Abstract
The gamma rays and conversion electrons following the gamma decay of 141Ba obtained by mass separation of 235U fission products have been measured. The main features of the 141La level scheme were established on the basis of gamma-ray energies and intensities, internal conversion electron measurements and quantitative and qualitative gamma - gamma coincidences. A total of 144 gamma rays have been identified as belonging to the 141Ba decay. Conversion coefficients were determined.
