Charge state distribution of ^{86}Kr in hydrogen and helium gas charge strippers at 2.7  MeV/nucleon

Charge state distribution of ^{86}Kr in hydrogen and helium gas charge strippers at 2.7  MeV/nucleon

The charge state distributions of krypton (^{86}Kr) with an energy of 2.7  MeV/nucleon were measured using hydrogen (H_{2}) and helium (He) gas charge strippers. A differential pumping system was constructed to confine H_{2} and He gases to a thickness sufficient for the charge state distributions t...
