40Ca(p,d) analysis |

Analysis of run0072 (two hours accumulation).
Attachment 1:
Reconstructed beam image. The ring should correspond to the cell's frame.
Attachment 2:
Definition of cuts. The central region of the target was selected and then named "targ".
Attachment 3:
Particle identification. Deuterons are well separated.
Attachment 4:
Elab-theta plot. The target and deuteron cuts were applied. Kinematics curves of the (p,d) reactions are seen.
Attachment 5:
Elab-theta again. Calculated kinematics curves were superimposed.
An energy correction factor of 0.8 has to be introduced to reproduce the curves (probably due to the incomplete energy calibration).
In addition to the ground-state transition, excited states with spectroscopic factors larger than 0.4 are also shown. See PRC 48, 95 (1993) for the details.
Attachment 6:
Angular distribution of 40Ca(d,p)39Ca(1/2+) from the reference. A similar oscillating pattern was observed in the Elab-theta plot.
EDIT: the deviation from the kinematics was due to an incorrect beam energy. |
