138CE DG CC$FROM BrIcc v2.3a (10-Sep-2014) 2008Ki07, "Frozen Orbitals" appr.
138CE c 1974Bu03: Source of {+138}Pr was prepared at JINR. Ions were separated
138CE2c and selected with an electromagnetic separator and implanted into
138CE3c aluminum foil. |g rays were detected with Ge(Li) detectors (FWHM=0.7
138CE4c keV at E|g=40 keV, 2.3 and 2.9 keV at E|g=1 MeV); conversion electrons
138CE5c were detected with a |b-ray spectrometer incorporating Si(Li)
138CE6c detectors (FWHM=2.5-3.0 keV at K788.7 line of {+138}Pr). Measured E|g,
138CE7c I|g, E(ce), I(ce), |b|g-coin. Deduced levels, J, |p, |g and |b
138CE8c branching ratios, conversion coefficients, |g-ray multipolarities. See
138CE9c also 1971Af05 from the same group.
138CE c 1971Ju01: Source of {+138}Pr was prepared by the (p,n) reaction on
138CE2c enriched {+138}Ce target in the form of cerium oxide or cerium
138CE3c chloride, bombarded with E=10 MeV protons. |g rays were detected with
138CE4c a Ge(Li) detector (FWHM=5 keV at E|g= 1 MeV). Measured E|g, I|g.
138CE5c Deduced levels.
138CE c 1970Ho28: {+138}Pr source was prepared by (p,p3n) reaction with
138CE2c 99.999% pure praseodymium dioxide target bombarded with 48-MeV protons
138CE3c from the McGill University Synchrocyclotron. |g rays were detected
138CE4c with a Ge(Li) detector. Measured E|g, I|g. Deduced levels.

138CE d 1951PrAA: Phys Rev 84, 1006 (1951)
138CE c The total average radiation energy released by {+138}Pr |e decay
138CE2c is 4442 keV {I20} (calculated by evaluator using the computer program
138CE3c RADLST). This value agrees well with Q(|e)=4437 keV {I10}
138CE4c (2017Wa10) and shows the completeness of the decay scheme.
138CE c The decay scheme is that of 1974Bu03
138CE d The evaluator has removed the 2593 level in previous evaluation
138CE2d (2003So13) originally added in the evaluation by 1976Pa04 on the basis
138CE3d of energy fit, since there is not any experimental evidence for the
138CE4d existence of this level.
