|
Run 51 to 61 are converted and analysed.
I fixed the gamma/no gamma normalisation after binning change.
We clearly see :
a state at 2.5 MeV that decay directly to the g.s. and a state at around 5 MeV with a 3 gamma cascade.
To do list:
- Add an angle dist in AngDist.C macro for the states around 2MeV (you can remove the Ex plot)
- Put Logy in all the canvas for the angle dist;)
- create a new macro showing the EDC 1D histo gated on several sliding windows in Ex to see the the gamma peak changing height
- add arrow or line indication the gamma rays position on every plots
- build the level scheme based on this (there is a preliminary scheme posted earlier by Manu based on gamma-gamma). |

we loose the beam around 11:12, it should be back in few minutes according to pcp.
11:18: the beam is back (3.5E5 pps) |

A security problem occurs at a door near CSS1 ( AFR alarm ), need to call the security to fix the problem
The person needs to come so it will take ~1h |

|
- Updated the macro for the angular distributions.
- For the angular distribution of the peak at 4 MeV excitation energy I think we need the calculation for the transfer 0f5/2.
- Added the gamma spectra gated on the 3 main peaks in Ex in the macro DrawPlots.C (arrows and labels of the gamma should be added). |

|
In response to Franco's comment here, I ran some quick TWOFNR simulations for a 0f5/2 transfer on to 4 MeV, on to spin 2 or 3. The attached files are named as follows:
24.f52_4MeV_sp3 - Transfer via 0f5/2 on to a spin 3 state at 4 MeV
24.f52_4MeV_sp2 - As above, but spin 2.
See the attached image for a plot of these two results, compared to a 1p3/2 transfer to 143keV, spin 2, and a 1p1/2 transfer to 1984 keV, spin 1.
Hope these are helpful! |

Bertrand saw that the slits were slightly closed, called the PCP and now we have around 5e5 pps

Fixed, e793s, Sat Mar 13 19:54:47 2021, Louis, Sarah, OFFLINE, General, CD2, Preliminary spectroscopic factors
|
1) Preliminary spectroscopic factors has been extracted for the first 2- exited state @ 143 keV and for the 0- excited state @ 1985 keV. DWBA calul has been performed by cyril for a p3/2 transfer at 0MeV and a p1/2 transfer at 2MeV. Experimental differential cross section has been extracted by normalising the number of counts with the total number of incoming 47K (from CATS div), the number of deuteron in the target, and correcting from MUGAST geometrical efficiency (computed by franco for the gs) and from AGATA efficiency (with the energy depence given by Emmanuel). The 1p3/2 C2S of the first 2- state was found to be 0.22. The 1p1/2 C2S of the 0- excited state was found to be 0.88.
2) gg analysis from Chloé identified a new transition at 997keV in coincidence with the 143 keV gamma. Ex spectra gatted on the 997 keV transition is shown. One can identified a clear state at about 1.1MeV corresponding to the 998+143 gamma cascade. A second clear state is identified at 2.2 MeV but no 1.2MeV gamma has been identified to complete the gamma cascade of this state.
3) the usual analysis plots updated with full statistics. |
