C161000100010 PART-DET (G,DG) C161000100011 DETECTOR (GE) N-type Ge detector with 100% relative efficiency C161000100012 located at 90 degrees with its cryostat front face 5 C161000100013 cm from the center of the cell. C161000100014 SAMPLE (2-HE-3,ENR=0.99999) The nickel entrance foils were 1- C161000100015 microm in nominal thickness, glued onto the nickel C161000100016 foil holders. Fresh foils were used for most C161000100017 bombarding energies. Foil thicknesses were measured C161000100018 to +-1% using the 3.2-MeV alpha particles from 148Gd. C161000100019 ANALYSIS Cross sections were converted to S factors using the C161000100020 relation S(Ecm)=sigma(Ecm)*Ecm*exp((Eg/Ecm)**0.5), C161000100021 where Eg**0.5=164.13 keV**0.5. C161000100022 ERR-ANALYS (ERR-T) The tabulated uncertainties in the S factors C161000100023 and their ratios include statistics, the +-1% C161000100024 variable systematic uncertainties, and the C161000100025 contribution of the uncertainty in the mean reaction C161000100026 energy Ecm-the latter is important only at the lowest C161000100027 bombarding energy. C161000100028 (ERR-1) variable systematic uncertainty. C161000100029 DECAY-DATA (4-BE-7,53.22D,DG,478.,0.1044) C161000100030 HISTORY (20160629C) BP C161000100031 (20220717A) OS.

The gamma0 C161000300004 yield was obtained by summing the counts in a C161000300005 background-subtracted window around the full-energy C161000300006 peak, and the 429-keV yield in a 7Be compound nucleus C161000300007 was determined by fitting the peak shape with the C161000300008 same function used for fitting the source lines and C161000300009 the 478-keV line in 7Li.
