Title: Shell model study on exotic nuclei and uncertainty analysis on liquid drop model

Speaker: 袁岑溪博士,中山大学

Abstract:

Many exotic properties are found in the proton- and neutron-rich nuclei near the drip line. Shell model study are performed on these properties, including binding energies, electromagnetic moments and transitions, and β decay. In the proton-rich side, nuclei around A=20 are well described when the weakly bound effect of proton 1s1/2 orbit is included. In the neutron-rich region, the psd shell nuclei are systematically investigated through a new Hamiltonians.

The statistical and systematic uncertainties of liquid drop model (LDM) are investigated under simple statistical assumptions. Two uncertainties are assumed to be normal distribution and obtained through the residues between LDM and observed data. The statistical results are agreed with the physical consideration, such as the residue of light and closed shell nuclei distribute mostly inside the systematic uncertainty which means they are not well described by LDM.
