+If we assume a normalized emittance of 0.6 π mm mrad provided from ReA3 at 3.0 MeV/u the geometric emittance is 0.6/0.08 = 7.5 π mm mrad.\\
-Geometric emittance is 0.6/0.08 = 7.5 π mm mrad.\\
+With the spot size on the target, designed to be ±0.5 mm (1σ), the anglular spread then is ±15 mrad.\\
-Spot size on the target is ±0.5 mm (full width). Then anglular spread is ±15 mrad.\\
+Adding the calculated spread from the reaction with the target of 0.13 deg = ±2.26 mrad we get ±17.26 mrad of angular spread.\\
-Adding the effect from the target of 0.13 deg = ±2.26 mrad we get ±17.26 mrad of angular spread:\\
