This search was triggered by our lack of seeing the 3958keV line at the expected level. 2689 keV line observed (runs 112,115,116) as 55-60 counts. Expected
yield in 3958 keV line based on 80:20 branching and 1.5:1.0 efficiency is 10 counts. We see (at most) 2 in the full photo-peak for this line. (Theses two
counts are also lower than expected by about 20 keV.)

Further to the previous post on gamma-ray lines, attached is Kanungo's paper on doppler-attenuation measurement of the 4033 line for lifetime measurement.
The lower-energy lines are, however, not included in the figures. |

In the reaction 15N(7Li,t)19F, the ratio between the measured cross sections is R(3/2+/9/2-)>29. We should get the same ratio in 19Ne. In 19Ne, the 3/2+
state decays with Eg=4033 keV (80%), the second with 2632 keV (100%), gamma efficiency = 4% and 5.5%, this gives a ratio between the number of counts measured
in the 2632 keV and in the 4033 keV > 29 x 100/80 x 5.5 / 4 ~ 50. |
