Identification of exotic reaction channels in 238U+238U

The aim of the experiment was to produce and identify neutron-rich nuclei in the uranium region by multi-Nucleon Transfer (MNT) aiming at a particle identification in atomic mass A by VAMOS and an atomic chargeidentification by X-ray detection in a set of three Low Energy Photon Spectrometers (LEPS) in the reaction 238U+238U at above-Coulomb barrier energies. The VAMOS setup was equipped with a new target chamber accommodating the three LEPS X-ray detectors anda second arm including the HARPEE particle detector. VAMOS was equipped with new MWPC detectors. The germanium detector AGATA was used to investigate the nuclear excitation structure of the detected nuclei.

E810_20 - 本实验旨在通过多核子转移（multi-Nucleon Transfer, MNT）反应产生并识别铀区富中子核素；在高于库仑势垒能量下的²³⁸U+²³⁸U反应中，利用VAMOS进行原子质量A的粒子鉴别，并通过三套低能光子谱仪（Low Energy Photon Spectrometers, LEPS）的X射线探测实现原子电荷鉴别。VAMOS装置配备了新的靶室，可容纳三台LEPS X射线探测器，以及包含HARPEE粒子探测器的第二臂。VAMOS还配备了新型多丝正比室（MWPC）探测器。锗探测器AGATA用于研究所探测核素的核激发结构。
