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. |

goal: we want to check whether the yields of the 1297.7 keV (from 19Ne 1536, 3/2+, l=1 state) and 1340 keV (from 19Ne 1615, 3/2-, l=2 state) g-ray lines
is compatible with what we expect from x-sec calculations

|
Figures above, simulation of VAMOS acceptance for 10+ and 9+ 19Ne charge states. Ratio between them quite big (0.58)
Figures below, comparison of the states with offline data. Ratio much smaller.
It seems like acceptance doesn't cut the 10+ charge state too much, but 10+ is less produced than 9+. |

When VAMOS VXI crashed (run 118) the Action file was recompiled.
As AGATA conversion is not copying the ACTION file for each run, it used the old version by default (from 16th of july).

Looking at AGATA count rate, we have seen that the highest counting rate for 511 keV line is seen in the inner ring (0*A clusters).
The outer ring detectors (10B for example) counts 10 times less.
