General Comments:

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.

E(level): From least-squares fit to Eγ data by the evaluator, except as noted. E=44.2 keV, and 149.9 keV have been held fixed during the the least-squares fit. ΔE=1 keV for gammas without uncertainty is assumed

Jπ(level): Except as noted, assignments are based on band structure

E(γ): From Coulomb Excitation (2016JaZZ, 1999Wi11), except as noted
