Ground-State Energy Shifts of H-Like Ti Under Dense and Hot Plasma Conditions

【摘要】 <正> In this study,by adopting the ion sphere model,the self-consistent field method isused with the Poisson-Boltzmann equation and the Dirac equation to calculate the ground-stateenergies of H-like Ti at a plasma electron density from 10²²cm^-3 to 10²⁴ cm^-3and the electrontemperature from 100 eV to 3600 eV.The ground-state energy shifts of H-like Ti show differenttrends with the electron density and the electron temperature.It is shown that the energy shiftsincrease with the increase in the electron density and decrease with the increase in the electrontemperature.The energy shifts are sensitive to the electron density,but only sensitive to the lowelectron temperature.In addition,an accurately fitting formula is obtained to fast estimate theground-state energies of H-like Ti.Such fitted formula can also be used to estimate the criticalelectron density of pressure ionization for the ground state of H-like Ti.更多还原
