239PU c  A {+239}Np source was produced by neutron activation of {+238}U (six   
239PU2c  hours of irradiation) at the research reactor in the University of     
239PU3c  Pavia. The produced {+239}Np sample (1050 Bq) was dissolved in a       
239PU4c  liquid scintillator and sealed in the Teflon container. The half-life  
239PU5c  of the metastable state of {+239}Pu was measured from the time         
239PU6c  distribution between |b{+-} particles detected by the scintillator     
239PU7c  and the delayed events of internal conversion electrons or |g-rays     
239PU8c  detected by the scintillator or a HPGe detector.
