147PM c The {+147}Nd isotope was identified by 1946Bo25 in
147PM2c {+146}Nd(n,|g),E=thermal reaction, with measurement of its half-life as
147PM3c 11.1 d {I2}, in agreement with the recommended value of 11.03 d {I3}.
147PM4c Earlier, 1941La01 (also 1942Ku03) had identified a 10-d activity in
147PM5c neodymium formed by bombarding Pr, Nd and Sm metals by |a particles,
147PM6c 10-MeV deuterons, neutrons and |g rays. From current half-life values
147PM7c for Nd isotopes, this activity could only belong to {+147}Nd. Firm
147PM8c confirmation for the isotopic assignment of 11-d activity to {+147}Nd
147PM9c was made by 1947Ma28.
147PM c {+147}Nd source was prepared using {+146}Nd(n,|g),E=thermal reaction
147PM2c in almost all the studies.
147PM c Note: this decay is important in fission yield determinations, reactor
147PM2c applications and in monitoring activity from long-lived fission
147PM3c fragments, such as by the CTBTO group. In particular, precise and
147PM4c accurate emission probability of the 531-keV gamma ray is needed for
147PM5c such applications. To address this requirement, recent experiments to
147PM6c measure absolute intensities (per 100 decays of {+147}Nd) have been
147PM7c carried out at three laboratories:
147PM8c LNHB-CEA, Saclay; LLNL + Texas A&M + ANL collaboration; and NPL, UK.
147PM9c However, final results are available only from LNHB-CEA, Saclay work in
147PMAc 2020Ke08, which are included in the present evaluation. Preliminary
147PMBc results are available from LLNL in 2020KoZZ report, which are also
147PMCc listed here in comments. In October 2021, evaluator
147PMDc also received preliminary results from NPL, UK experiment through a
147PMEc private communication, but these results are not listed here. We hope
147PMFc to revisit the evaluation of this decay when final results from
147PMGc 2020KoZZ, and from NPL, UK become available in open literature

147PMxc 1978Ha22, 1967Ew01
147PM c 2013BeZP: DDEP evaluation of {+147}Nd decay, with a literature
147PM2c coverage up to March 2011. The evaluation presented in this dataset
147PM3c differs in many ways from the DDEP evaluation.
147PM c Main references for E|g, I|g, |g(|q) and |g|g(|q) data:
147PM c 2020Ke08: {+147}Nd source produced in {+146}Nd(n,|g) at the SmallBeBe
147PM2c facility in Delft, followed by separation and purification procedure
147PM3c using High Performance Liquid Chromatography (HPLC) coupled with an
147PM4c Inductively Coupled Plasma Mass Spectrometer (ICPMS) at CEA-Saclay.
147PM5c Absolute activity of the source was measured at CEA-Saclay by two
147PM6c methods: 1. 4|p|b-coin using liquid scintillator for |b and NaI(Tl)
147PM7c detector for |g radiation; 2. 4|p|g counting using a well-type NaI(Tl)
147PM8c detector. High-resolution |g spectra were measured for two sets of six
147PM9c sources each one (series 1) using activity before purification and the
147PMAc other (series 2) after purification using a 100 cm{+3} HPGe detector,
147PMBc calibrated in efficiency to 0.4% above 100 keV and 1-2% below 100 keV.
147PMCc Weighted averages of the two sets of absolute photon intensities were
147PMDc reported for K{-|a2}, K{-|a1}, K{-|b1} and K|b{-2} x-rays, and 22 |g
147PMEc rays from 91 to 686 keV, including two extremely weak |g rays of 357.7
147PMFc and 366.5 keV, and with no evidence for the existence of 80.82, 117.9,
147PMGc 159.7, 240.5 and 649.0 |g rays reported in 1997Sa53. The 80.82|g was
147PMHc interpreted as an escape peak of the strong 91.1|g. Absolute
147PMIc intensities of K{-|a} and K{-|b} x-rays were also measured. Results
147PMJc from this work have been included in the present evaluation.
147PM c 2020KoZZ: LLNL, Texas A&M and ANL collaboration. Mass-separated
147PM2c {+147}Nd ion beam produced in fission by the CARIBU facility at ANL was
147PM3c implanted on a thin carbon foil. Measured |b, ce, |g, |b|b-coin using
147PM4c a 4|p gas proportional counter for |b and ce (developed at LLNL), an
147PM5c HPGe detector with a superior efficiency response determination to
147PM6c 0.5% in E|g=50-2000 keV region at Texas A&M. GEANT4 simulations were
147PM7c carried out for the detector systems. From |b|g-coin, total |b
147PM8c activity, and efficiency curves for |g and |b detection, absolute
147PM9c photon intensities were determined for 12 strong |g rays from 91.1 to
147PMAc 695.9 keV, with 0.4% precision for the 531|g and 1.4% for the 91.1|g.
147PMBc Earlier results were also reported in Ph.D. thesis by A.M. Hennessy
147PMCc (University of California, Irvine, 2018). Results from this work have
147PMDc been quoted in comments, as these are still at a preliminary stage.
147PM c 1997Sa53: measured E|g, I|g, E(ce), I(ce) using HPGe
147PM2c and miniorange spectrometer. A total of 27 |g rays were reported based
147PM3c on singles data only. Evaluator has omitted six of these in this
147PM4c dataset, as these were either not confirmed in complementary decay
147PM5c or in-beam |g-ray studies, or were too low in energy resulting
147PM6c in severe transition-intensity imbalances.
147PM c 1995Go44: measured E|g, I|g, |g|g-coin. Total of 15
147PM2c |g rays reported.

147PM2c |g|g(|q). A total of 14 |g rays were reported. The |g-ray energies
147PM3c were measured with reference to previous E|g values from curved-crystal
147PM4c diffraction spectrometer (1967Hi04)
147PM c 1977Al34: measured |g(|q,t) from polarized {+147}Nd nuclei,
147PM2c and using low temperature orientation method. Also measured
147PM3c |g|g(|q) using Ge and Ge(Li) detectors; deduced J|p and
147PM4c mixing ratios.

147PM c 1974Ra30: measured E|g, I|g using Ge(Li) detector, and sum-coin
147PM2c spectrometer using NaI(Tl) detectors. A total of 13 |g rays reported
147PM3c from Ge(Li) singles data, and another 19 reported from sum-coincidence.
147PM4c None of the latter 19 |g rays has been confirmed in other studies,
147PM5c thereby rejecting levels proposed at 182, 228, 275, 319 and 725 keV.
147PM c 1971Si20: measured E|g, I|g, level half-lives by |b|g(t) and |g|g(t).

147PM3c (I|g=0.24 {I9}) reported in this work is discarded as 312.6|g is
147PM4c not confirmed in other studies. A |g ray of E|g=299.7 {I8} and
147PM5c I|g=0.67 {I28} is also discarded, as no such |g ray was seen in
147PM6c more recent studies.
147PM c 1967Hi04: measured E|g, I|g, |g|g-coin for 14 |g rays. Energies of
147PM2c eight |g-rays were measured using curved-crystal diffraction
147PM3c spectrometer. Other |g rays were measured using Ge(Li) detector. In
147PM4c authors' Table 2, measured upper limits (relative to 100 for 531|g)
147PM5c for the following |g rays which were reported in various studies
