By using the full-core plus correlation (FCPC) type wave functions,the accurate charge densities ρ(0) at the nucleus and the radial expectation values of the ground states for the lithium-like systems with Z= 21 to 30 are obtained.The determinantal conditions and the electron-nucleus cusp condition are used to calculate the inequalities of the upper and the lower bounds to ρ(0) with two or more expectation values.These inequalities,

The real-time investigation of the ultrafast dynamics of molecules in gas and condensed phases has attracted a great deal of attention.The deactivation processes of electronically excited molecules in
Time-resolved photoelectron spectroscopy (TR-PES) has been proven as a powerful means for elucidating electronic dynamics of molecules in the gas phase.It would be highly interesting to apply this met
