Valerian | OFFLINE | General | CH2 | Oxygen 15 excitation function |
| After a quick analysis, we can conclude that MUST2 is working for resonant elastic scattering. We find a resolution of 125 keV which will improve with a better analysis, as we are using a basic calibration for CsI Energy. |

Valerian | TARGET | General | CH2 | Problem with the target for run 2004 and 2010 |
The target seems identical between the two runs... We will have to investigate to understand what is going on.
The decision is to change the target 5 for the target 4 104um from georges.
The two spectras from run 2003 (target nr6) and 2010 (target nr 5) are identical. The peak at low energy correspond to the first excited state in 15F.
In the picture, target N°4 is written 104 µm
N°5 100 µm GoodFellow
N°6 187µm |

Iulian Valerian Pedjia | TARGET | General | CH2 | Target issue No5 |
In the attached figure it could be seen that with the target No5 (run 2010) lower energy resonances were visible (lower part of the figure), which is not the case with the target No4 (upper part)from run 2013.
GOODFELLOW or mounting error? |

Valerian and Iulian and Francois | OFFLINE | General | CH2 | First picture for 15F from runs 2010-2013 |
Target -> Thick target (Sandwich target ??)
The predictions are different....
At large angles, the 5/2+ peak (at 2.78 MeV) is cut because it goes to lower energies in lab. If the background at 4 MeV is normalized to the one at 0°, there is no very broad-resonance at high energy in large angles. |
