Identification:
1954St98: 244Pu produced from 243Pu(n,γ) reaction and possibly by electron capture of 244Am. The reaction were studied via a multiple order neutron capture of 239Pu in the pile irradiated plutonium experiment at the Material Testing Reactor at Argonne National Laboratory with integrated flux of ×104 neutrons. Plutonium was chemically separated and analyzed in a 12 inch, 60 |’ mass spectrometer.
