Preliminary analysis of the 37K(d,t)48K reaction. The 1944keV gamma transition is identified. Excitation energy was extracted using a cut on E-Tof Id in MUST2. More precise time calibration has to be performed on MUST2 to go further.

Fanstastic work, Emmanual and Chloe thanks. In a previous version, the 3522 was put in coincidence with the 143, but this has now changed?

1) Summary of the the Ex vs Eg analysis with all the gamma ray identified highlighted in red. Green line shows the corresponding position of the excited states.

2) C2S extracted from DWBA analysis for the 0.143 (p3/2), 1.130 (p1/2), 1.985 (p1/2) and the 4 MeV (f7/2) states

3) A gamma ray transition is observed from the unbound states of 48K. Interesting is to notice that this 367 keV transition appear only for those states and that no high energy gamma are observed here.

4) usual Analysis plot



=> as regard as the unbound 48K*>Sn at 6MeV, the gamma ray at 361keV comes from the 1st excited state in 47K.
the other low gamma ray (2234keV) is not observed in coincidence with Eg=280keV or Eg=143keV.

the slit L5 was opened around 18h to increase the yield and closed back a bit 10 min later (to 17pi) because CATS seemed to saturate

We asked for a beam intensity increase around 01h10
The slits L5 were opened and more power (~ 100 W) on primary target
Now ~ 5.6e5 pps on Cats2
