Strontium isotopes

Strontium and barium isotopes in presolar silicon carbide grains measured with CHILI—two types of X grains

We used CHILI, the Chicago Instrument for Laser Ionization, a new resonance ionization mass spectrometer developed for isotopic analysis of small samples, to analyze strontium, zirconium, and barium isotopes in 22 presolar silicon carbide grains. …
