Peculiarities in fragment mass distribution in the + (243 MeV) reaction
A pronounced fine structure (FS) in the form of distinct peaks was
observed in neutron gated mass spectra from the decay of the 110 composite
system produced in the reaction + (243 MeV) at an initial
excitation energy MeV. The FS peaks are located in the vicinity
of mass numbers 70-80, 100, and 130, which correspond to those of magic
nuclei (clusters). In the data there is also evidence for a new type of
decay -collinear cluster tripartition of an excited nucleus
