Descripción
The influence of the orientation angles of the target nucleus symmetry
axis, relative to the beam direction, on the production of the
evaporation residues is investigated for the
48Ca+154Sm reaction as a function of beam energy.
At low energies (Ec.m.<137 MeV), the yield of evaporation
residues is observed only for collisions with small orientation angles
(αT<45\circ). At large energies (about
Ec.m.=140--180 MeV), all orientation angles
αT can contribute to the evaporation residue cross
section σER in the 10-100 mb range. At
Ec.m.>180 MeV, σER ranges approximately
0.1-10 mb because the fission barrier for a compound nucleus decreases
with increasing excitation energy and angular momentum.
