For improved cross-section measurements of the reaction 4He(3He,gamma )7Be in inverse kinematics, the recoil mass separator ERNA (European Recoil separator for Nuclear Astrophysics) is used to detect directly the 7Be recoils with high efficiency. The 7Be recoils are produced by the 4He projectiles in a windowless 3He gas target. ERNA fulfils the requirement to study the reaction over the center of mass energy range Ecm= 0.7-3 MeV. In the energy range Ecm=1.1-3 MeV ions identification is performed with Delta E-ERest telescope detector, while in the energy range Ecm= 0.7-1.1 MeV a TOF-E detector is needed.

Abstract
For improved cross-section measurements of the reaction 4He(3He,gamma )7Be in inverse kinematics, the recoil mass separator ERNA (European Recoil separator for Nuclear Astrophysics) is used to detect directly the 7Be recoils with high efficiency. The 7Be recoils are produced by the 4He projectiles in a windowless 3He gas target. ERNA fulfils the requirement to study the reaction over the center of mass energy range Ecm= 0.7-3 MeV. In the energy range Ecm=1.1-3 MeV ions identification is performed with Delta E-ERest telescope detector, while in the energy range Ecm= 0.7-1.1 MeV a TOF-E detector is needed. The commissioning of the TOF-E (Time of Flight-Energy) detector set up and the first observation of the 7Be recoils are reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
