Surface Diffuseness

A simultaneous description of nuclear form factors and momentum distributions for ground and collective excited states is presented using a simple liquid drop model with an oscillating nuclear surface. The influence of the nuclear surface diffuseness over nuclear form factors and nucleon momentum distributions for a large region of mass number is investigated. Mean square radii of nuclei in one-phonon excited states are discussed. Quasi-elastic electron scattering y-scaling functions are presented and compared with those extracted from experimental data.

Model Approach

Proton partial occupancies of the nuclear surface orbits are used in a modified shell model approach to study isoscalar dipole transition charge densities and form factors for self-conjugate nuclei. The energy-weighted sum-rules of Harakeh-Dieperink for both the transition form factor and transition charge density are modified so as fractional occupation probabilities of the states may be used. The partial occupancies of the surface n/j-levels are determined by fitting to the experimental inelastic scattering data and compared with those found previously in the study of nuclear ground state properties

Nuclear Phases

Taking the magnitude of the elements of the S matrix and the nuclear phases to be of Woods-Saxon form in the variable I with width parameter LI, we find that the form of the scattering amplitude components f+(B) and f-(B) is specified by the parameters LI+ and LI- such that LI is closely the geometric mean of LI+ and LI-. Many angular distributions have been analysed into f+(B) and f-(B) to obtain LI+ and LI- and hence LI, the angular momentum diffuseness, from which the nuclear surface diffuseness is obtained, so reducing an ambiguity in the nuclear potential. The case of light ions incident on heavy ions has also been investigated.

The Moment

A systematic investigation of collective properties in the nuclei of an [Formula: see text]-decay chain from [Formula: see text]Po to [Formula: see text]Cn has been performed in the total-Routhian-surface calculations. The empirical indicator [Formula: see text]-factor, energy ratio [Formula: see text], and the energies of the first excited state [Formula: see text] exhibit a hint about nuclear deformation or shape transition in these nuclei. The calculated results of ground state equilibrium deformations are compared with the previous study and available experimental data, showing a general agreement. In addition, the upbending behaviors in moments of inertia have been reproduced by the present work. It is found that the similar alignment of a neutron [Formula: see text] pair is mainly responsible for the upbending in the heavier nuclei. The gentle increasing angular momentums reveal the delayed alignment to certain high spins. Furthermore, taking the near proton drip-line nucleus [Formula: see text]Cn as an example, we briefly discussed the influence of the modification of Woods–Saxon potential parameters (e.g., the strength of the spin-orbit potential [Formula: see text] and the nuclear surface diffuseness [Formula: see text]) on the moment of inertia. This may imply the role of the slight parameter modifications is negligible due to almost unchanged deformation and pairing interactions at ground state.
