博士 === 國立臺灣大學 === 物理研究所 === 94 === Photoionization parameters in neutral beryllium are calculated in the multiconfiguration relativistic random-phase approximation to resolve the interplay between relativistic and correlation effects in low-Z atoms or ions. Precise energies and widths of five Rydberg series of low-lying doubly-excited states are given. Experimental studies on angular distribution of photoelectrons are suggested to obtain information on widths of some states, which cannot be obtained from total cross section measurements.
