Vv. Belaga et al., SEARCHES FOR THE COHERENT FRAGMENTATION OF CARBON NUCLEI INTO 2-ALPHA-ALPHA+T+P STATES AT 4.2 GEV(2D AND 2)C PER NUCLEON/, Physics of atomic nuclei, 60(5), 1997, pp. 791-795
Coherent-dissociation reactions C-12 --> 2 alpha + 2d and C-12 --> 2 a
lpha + t + p on carbon nuclei at 4.2 GeV/c per nucleon are sought, and
the cross sections for these reactions are estimated. The momentum an
d correlation features of secondary fragments in the laboratory frame
and in the c.m. frame of a fragmenting nucleus are analyzed and compar
ed with the corresponding data on the reaction C-12 --> 3 alpha.
