Study of the cluster structure of light nuclei including radioactive ones in relativistic-fragmentation processes is a topic of the project BECQUEREL which continues the tradition of use of the technique track emulsion (NTE). Such reactions are under study by means of NTE stacks longwise exposed to primary and secondary beams of relativistic nuclei of the JINR Nuclotron. Coherent dissociation...

Spectroscopy of the heavy helium isotope He6 have been studied in reactions of stopped pion absorption by light nuclei. Experiment was performed at low energy pion channel of the LANL using two-arm semiconductor spectrometer. Search for nuclear states was performed in inclusive and correlative measurements of missing mass spectra. Excited states of the He6 were observed in two- and three body...

A series of experiments has been performed at Flerov Laboratory of Nuclear Reactions (JINR) on measurement of total cross sections for reactions 4,6He+28Si and 6,7,9Li+28Si in the beam energy range 5-40 A·MeV. The transmission method based on registration of energy loss in the material of ∆E detector (Si target) as well as registration of n-γ radiation by the 4π spectrometer was used. The...

In a series of the experiments at different time-of-flight spectrometers of heavy ions we have observed manifestations of a new at least ternary decay channel of low excited heavy nuclei. Due to specific features of the effect, it was called collinear cluster tri-partition (CCT). The experimental results obtained initiated a number of theoretical articles dedicated to different aspects of the...

In March of 2017 the A2 collaboration at MAMI microtron (Mainz, Germany) has taken the data on meson photoproduction on liquid deuterium target at tagged photon energies up to 1.5 GeV. The main aim of the experiment is to perform a high statistics study of neutral pion and η-meson production on free neutron. The measurements will greatly improve the available database on neutron target and...

Structure of nuclei located near and beyond the drip-lines plays important role
in the explosive astrophysical processes.
The problem of two-proton decay of the $^{17}$Ne first excited state is a good example of such situation.
The two-proton radiative capture is a possible bypass of the $^{15}$O waiting point in the rp-process.
The rate of this process drastically depends on the...

Using radioactive beams to explore nuclei far from the $\beta$-stability line has sparked intensive experimental and theoretical studies of neutron-rich nuclei during recent years [1]. In addition an attention has been devoted to effects of varying the ratio between the proton $Z$ and neutron $N$ numbers on different nuclear structure characteristics of nuclei deviated from their valley of...
