High-energy direct reactions
In the vicinity of the neutron dripline, the final states are generally unbound and, as such, all in-flight decay products of the beam (charged quasiprojectiles, neutrons and, in some cases, gamma rays) must be detected and their pulses measured. This allows the construction of the invariant mass (or relative energy) spectrum as well as other variables of interest, such as the relative neutron-neutron pulse. The device used to perform these measurements at RIBF includes the SAMURAI magnetic spectrometer (7 Tm) coupled to the NEBULA multidetector made of plastic scintillators, which was completed in 2016-17 by the NeuLAND demonstrator. If needed, the DALI2 (NaI) or CATANA (CsI) multidetectors are used for the detection of the de-excitation of excited states of quasi-projectiles.
