245CM c 2019Ah02: The measurements were done in the early 1970s
245CM2c where gamma rays were detected using a Ge(Li) detector.
245CM3c The data taken in the 1970s were analyzed by the authors and the
245CM4c {+245}Am decay scheme was deduced and extended from prior
245CM5c known level scheme.
245CM c 1968WaZZ: {+245}Am the daughter product of {+245}Pu that was
245CM2c produced at the Oak Ridge Research Reactor from
245CM2c neutron incident on enriched {+244}Pu. Gamma rays were measured
245CM3c with a Ge(Li) detector with a FWHM=2.48 keV for 1.332-MeV |g rays.
245CM c 1967Bu09: The gammas were detected with Ge(Li), Na(Tl) and
245CM2c Si(Au) detectors and their intensities relative to the |b decay
245CM3c rate were determined with a gas-flow proportional counter.
245CM4c Conversion electron spectra were measured with a Si(Au) detector.
245CM5c Determined absolute intensity of the 252-keV |g-ray
245CM c 1955Br02: Beta spectrum was studied with a thin lens magnetic
245CM2c spectrometer. Gammas were measured with NaI(Tl) detectors. Measured K
245CM3c and L conversion lines, |g, |g|g-coin. Proposed preliminary level
245CM4c scheme with a total disintegration energy of 1.32 MeV
