Nuclear fusion as a probe for octupole deformation in $^{224}$Ra
Abstract
: Nuclear fusion has been shown to be a perfect probe to study the different nuclear shapes. However, the possibility of testing octupole deformation of a nucleus with this tool has not been fully explored yet. The presence of a stactic octupole deformation in nuclei will enhanced a possible permanent electric dipole moment, leading to a possible demonstration of parity violation. : To check whether static octupole deformation or octupole vibration in fusion give qualitatively different results so that both situations can be experimentally disentangled. : Fusion cross sections are computed in the Coupled-Channels formalism making use of the Ingoing-Wave Boundary Conditions (IWBC) for the systems O+Ba and O+Ra. : Barrier distributions of the two considered schemes show different patterns. For the Ra case, the octupole deformation parameter is large enough to create a sizeable difference. : The measurement of barrier distributions can be an excellent probe to clarify the presence of octupole deformation.
