Properties of Titanium isotopes in complex momentum representation within relativistic mean-field theory
文献摘要：
The self-consistent quadruple potential is deduced within the relativistic mean-field(RMF)frame-work and substituted into the Hamiltonian,which is cal-culated using the complex momentum representation(CMR).Considering even-even titanium isotopes as an example,this study investigated various properties,including the resonant states of neutron-rich nuclei in the RMF-CMR model,and used them to describe the binding energy.The abrupt decrease in the two-neutron separation energy(S2n)corresponds to the traditional magic number.The resonant and bound states are simultaneously exposed in the complex moment plane,where the continuum is along the integration contour.The four oblate neutron-rich nuclei 72-78Ti are weakly bound or resonant because their Fermi energies are approximately 0 MeV.The root-mean-square(RMS)radii of these nuclei increase suddenly compared with those of others(neutron number N＜48).Moreover,78Ti and 76Ti are determined as drip-line nucleons by the value of S2n and the energy levels,respectively.Finally,the weak-bounded character can be represented by diffuse density probability distributions.
