AGATA - Data analysis

1
AGATA - Data analysis

• To start now, a realistic (general) Monte-Carlo
  is needed

2
Simulation based on level scheme
First version

• Input Radware files (.ags)
• Cascade randomly selected
• Converted ?rays included
• Selection between several LS

Available since september 2004
3
Improvements

• Input ENSDF files
• Feeding (very simple)
• Experimental filter

Life-time Radioactive decay Coulomb excitation
Available soon !
4
Why an experimental filter ?
?-rays / physics generator
Experimental Filter
Tracking
Data for analysis
GEANT
5
Experimental filter Euroball/Agata
?
Detected ?

Some recent results

• Fusion-evaporation experiment with 6 nuclei
• 151,152,153 Dy, 148,149 Gd and 151 Tb
• production cross sections 30, 50, 20, 1, 2 and
  20
• Excitation energy for all residus 80 MeV (no
  spin)
• Comparison Agata/Euroball
• symmetric (5) / asymmetric reaction (2)
• One billions of cascades
• 8 hours on a recent PC
