| dc.description | Durante la irradiaci6n con neutrones rápidos, en preparaci6n para estudios de determinación de edad por 40Ar - 39Ar, is6topos de cript6n son producidos de rubidio y estroncio presentes en minerales silicatos naturales. Mediciones de la razón 84Kr/86Kr en muestras irradiadas permite la determinación de su razón Sr/Rb que es un parámetro esencial al estimar lo adecuado de los minerales para su posible estudio de Rb-Sr. Interferencias por otros elementos que ocurren en la naturaleza son evaluadas y aparecen ser despreciables. | es-ES |
| dc.description | During fast-neutron irradiation in preparation for 40Ar - 39Ar age determination studies, krypton isotopes are formed from rubidium and strontium present in natural silicate minerals. Measurement of the 84Kr/86Kr ratio in irradiated samples admits the determination of their Sr/Rb ratio which is a parameter essential in evaluating the minerals for possible Rb-Sr studies. Interferences from other naturally occurring elements are evaluated and appear to be negligible. | en-US |
