|
Supplementary to Adrien's kinematic calculations of 47Ti(d,p)48Ti, we have found a paper suggesting that by far the most strongly populated state in 48Ti is at 5.65 MeV. There is also a doublet of strong states at around 4.4 MeV, and two more strongly populated states at 6.06 and 6.33 MeV.
See attachment for the full table from P. D. Barnes (1965), Phys.Rev.138.B597.
Some quick CatKin models also show that a (theoretical) state at 7 MeV in 48Ti would almost perfectly overlap with the ground state of 48K. As such, when looking at the lab energy with the g.s. of 48K normalised to 0, we could expect to see these strongly populated 48Ti states at -0.67, -0.94, -1.35 and -2.6 MeV (for 6.3, 6.06, 5.65 and 4.4 MeV, respectively).
See the attached plot for kinematics of 47K(d,p)48K @ 0 MeV and 4 MeV, as well as 47Ti(d,p)48Ti @ 0 MeV, 5.65 MeV and the theoretical 7 MeV. Additionally, see a mock-up of the expected spectra from Wilton. |

|
We noted that the gamma ray efficiency calculated from file converted from AGATA was close 100%. We concluded that the conversion program was reauiring a gamma ray to be present.
This is confirm by analysis of the ganil dta file that show 10 time more count that the agata one.
Here is a kinematical plot of the run 51 and 52 analysised from ganil file.
There is a 1.5MeV state present that disappear in the agata coincidence. This is to be investigated with more data. Is it an isomer state? from 48K? 48Ti? |

|
| at 2h50 beam intensity reached 1.1x10^6 pps in CATS for 6.5x10^5 pps in VAMOS. The transmition decreased to 60% without any shift of the beam position. Does it come from a loss of efficiency of VAMOS at high counting rate? |
