More statistics on the script written by Adrian and Valerian (first image)
Second image is a comparison between the excited states produced between 90-130 deg and 130-180 deg. Effects of angular distribution?
the kinematic line seen in the Elab vs Theta at backward angles can be observed in figure 3. Are those protons? |

A. Lemasson | OFFLINE | Software | | VAMOS Conversion HowTo |
HOW TO convert a run in VAMOS
- Do : source $HOME/GoToVamosAna
- To Convert a Run : MyVAna -d2Ar <RunNr>
- Otherwise, If you want to convert a single file : MyVAna -d2Ar -f <Infile> <OutFile>
- Output Root rile is written to : ./RootA/
If you encounter the error on Brho "Could not find the BrhoRef for the run <RunNr> ", Update the ./Calibs/ListBrho.dat file with relevant Brho for RunNr |

Measured :
Brho(6+) = 0.7473 Tm => E=4.9355 MeV/u => e=109.7 µm
Brho(5+) = 0.8924 Tm => E=4.8874 MeV/u => e=111.5 µm
Measured e=110.6 µm
N°3 CH2 100 µm Goodfellow (polyethylene)
Measured Brho(6+)=0.7754 Tm => E=5.3126 MeV/u
