Laser-Induced Isotopic Effects in Titanium Resonance
Titanium isotope ratios have been measured by resonance ionization mass spectrometry (RIMS) with special emphasis on the nature of laserinduced isotopic selectivity. A pronounced wavelength dependence of even mass isotope ratios is caused by large nuclear volume effects near the magic neutron number 28 in T i . Optical isotope shifts, ranging from 0.07 to 0.21 cm-l, between T i and 4eTi were me...
متن کاملLaser-induced isotopic selectivity in the resonance ionization of Os
Isotope selective effects in resonance ionization mass spectrometry (RIMS) pose a potentially serious limitation to the application of this technique to the precise and reproducible measurement of isotope ratios. In order to identify some of the underlying causes of isotope selectivity in RIMS and to establish procedures for minimizing these effects, we investigated laser-induced isotope select...
متن کاملEndemic Isotopic Anomalies in Titanium
Abundances. of the titanium isotopes were determined using a new high-precision technique that s~ows. terrestnal, lunar, an~ bulk meteorite samples to be indistinguishable. Ca-Al-Ti-rich inclusiOn~ m the Allende meteonte are found to contain Ti of widely varying isotopic composition reflectl.ng the :presence of at least three nucleosyJ?-thetic components. The anomalies in Ti appear to be rel!l-...
متن کاملSpectroscopic Characterization of Laser-induced Titanium Plume
A titanium target was ablated by a KrF excimer laser with fluences varying from 4 to 8 J/cm in an argon filled environment with pressures ranging from vacuum to 1 torr. The effects of laser fluence and background gas pressure on the kinetic energies of the ablated species were investigated by temporally and spatially resolved emission spectroscopy. The maximum surface temperatures were calculat...
متن کاملLaser-assisted and laser-induced electron-impact ionization during nonsequential double ionization of He
Two-electron sum-momentum distributions from nonsequential double ionization of He in an intense laser field are analyzed. The results of a S-matrix calculation show that the inelastic scattering of the first electron with the residual ion is best considered as a ~internal! laser-induced impact ionization. The parallel component of the sum momentum is found to be largest when the prescattering ...
