Analysis of run 63 to 89 in 40Ca(p,t)38ca reaction |
|
|
Here are some plot summarizing the analysis status on the 40Ca(p,t)38Ca channel.
Run concerned: 63-89
Running time: 18 hours
Gates applied:
- Target Impact (from CATS)
- Triton in dE-E
- Incoming 40Ca, TCATS2_HF in [1600;24000]
Plots:
- Cut applied
- Kinematics, Exitation energy and llaboratory angle for two possible pics
- Exitation energy per telescope for T1 to T4
Remarks:- There is no clear signal of ground state or any exited states
- One can mybe distinguish pics correspond to different states but badly separated
- During this beam time, Ionization Chamber was not working. Analysis of the 38Ca(p,t)36Ca reaction without this cut provide exactly the same shape of background. This background is probably due to fragmentation of the 40Ca beam in HAVAR foil, producing tritons undistinguishable from reaction tritond without cut on outgoing heavy ion.
Other runs in 40Ca with the CHIO are probably needed to make good Ex reconstruction and tritons calibrations
