------------------------------------
Measured Statistics (Run 256) about 10h:

GS + 1st excited:

MUGAST(Ex rec) : 2519 (bckg subtracted)
MUGAST(Ex rec + VAMOS) : 1282


Gamma(871keV) : 125 (if subtract bg only 80 cnts)
Gamma(871keV)+MUGAST(Ex) : 68
Gamma(871keV)+MUGAST(Ex)+ VAMOS IC: 27

Deduced gamma efficiency: 68/(2519/2) = 5.4 % ---> to be investigated

------------------------------------

Fit Results Excitation Energy (gated by VAMOS) - sum of two gaussian fit
