Assuming 200 Torr helium target., elastic and reaction peaks do not have signifcant overlap unless stated:

3um Ti, 1.88 MeV/u beam: Ecm=4.27-4.58 MeV

3um Ti, 2.2 MeV/u beam: Ecm=5.50-5.80 MeV

12.5 Al, 2.8 MeV/u beam: Ecm=3.41-3.72 MeV

2.5 um HAVAR, 1.88 MeV/u beam: Ecm=3.54-3.85 MeV (peaks overlap)

2.5um HAVAR, 2.2 MeV beam: Ecm=4.76-5.06 MeV

6um Ti, 2.2 MeV/u beam: Ecm=3.15-3.47 MeV

6um Ti, 2.8 MeV/u beam: Ecm=5.56-5.86 MeV
