Аннотация
The results of experiments devoted to studying fusion and transfer reactions in beams of loosely bound (3He) and cluster (6Li, 7Li) nuclei, as well as nuclei that have a halo structure (6He and 8He), with nuclei of light and heavy elements are generalized. Special features in the behavior of cross sections for the formation of evaporation residues and transfer-reaction products at energies near the barrier are revealed. The behavior of cross sections for nucleon- and cluster-transfer reactions leads to different populations of single-particle and collective states in target-like nuclei. The effect of various channels of nuclear reactions involving light nuclei on the population of the 195mHg and 197mHg(13/2+), 198mTl and 196mTl(7+), and 196mAu and 198mAu(12−) pairs of isomeric states is considered. The values of the isomeric ratios (σm/σg) for reaction products originating from fusion reactions followed by particle evaporation and from nucleon-and cluster-transfer reactions are explained.
