چکیده
The atomic structure of californium is probed by two-step resonance ionization spectroscopy. Using samples with a total amount about 2×1010 Cf atoms (ca. 8.3 pg), ground-state transitions as well to high-lying Rydberg states and auto-ionizing above the potential are investigated lifetimes various levels measured. These investigations lead identification efficient schemes, important for trace analysis nuclear investigations. Most measurements conducted on 250Cf. In addition, isotope shift isotopic chain 249?252Cf measured one transition. series enables determination first EIP=50,666.76(5)cm?1. This factor 20 more precise than current literature value.

Sub-Doppler UV spectroscopy by resonance-enhanced two-photon ionization: the structure of the benzene20,22Ne cluster
In this work it is demonstrated that mass selected multiphoton ionization is a powerful technique for high resolution spectroscopy, isotope cluster separation and investigation of the structure of van der Waals clusters. The rotationally resolved UV spectra of the benzene-“Ne and benzene-**Ne clusters are selectively measured in a natural isotopic mixture of benzene and benzene-Ne clusters in a...
متن کاملIndirect Determination of Ascorbic Acid by Atomic Absorption Spectroscopy
A new and simple method followed by atomic absorption spectrometry has been developedfor indirect determination of ascorbic acid (AA). The proposed method was based on the oxidationof AA to dehydroascorbic acid with Cu2+cation(200mgL-1)in an ammonium thiocyanatesolution atpH2.4. AA reduces Cu2+to Cu+followed by the precipitation of Cu+ with SCN-. Then, the excess ofCu2+in the solution was measu...
