CATLIFE (Complementary Arm for Target LIke FragmEnts): Spectrometer for Target like fragments at VAMOS++

Abstract

The multi-nucleon transfer reaction between 136Xe beam and 198Pt target at the beam energy 7 MeV/u was studied using the large acceptance spectrometer VAMOS++ coupled with the newly installed second arm time-of-flight and delayed γ-ray spectrometer CATLIFE (Complementary Arm for Target LIke FragmEnts). The CATLIFE detector is composed of a large area multi-wire proportional chamber and the EXOGAM HPGe clover detectors with an ion flight length of 1230 mm. Direct measurement of the target-like fragments (TLF) and the delayed γ-rays from the isomeric state helps to improve TLF identification. The use of the velocity of TLFs and the delayed γ-ray demonstrate the proof of principle and effectiveness of the new setup. © 2023
