Identification:

1983Po14: Pu irradiated with neutron followed by chemical extraction and measured by semiconductor γ spectrometry

1967Or02,1968Fi03:

^{244}Pu irradiated with α, followed by chemical extraction and measured γ-rays with Ge(Li) detectorExperimental work:

1987We01: Measured

^{248}Cm(^{129}Xe,X) and^{248}Cm(^{132}Xe,X) production cross-sections1974Ba73: Measured

^{248}Cm(t,αF) at E=16 MeV.Measured α singles and α-fission product coincidence spectra. α measured with ΔE-E counter telescope with energy resolution of 145 keV and the fission fragments were measured with fission detector. By using a statistical model, heights and curvatures for the peaks of double-humped fission barrier were deduced.
