内容記述 | Excess Ar-39 in olivine from neutron-irradiated mixtures of olivine and K-rich glass was measured to determine the amount of Ar-39 transferred by recoil out of the glass and into the surrounding olivine grains. It was found that a total of 9.0% of the total Ar-39 recoiled out of the 3-micron glass grains and 2.45% out of the 15-micron glass grains. The mean depth of Ar-39 depletion of the surface of the glass grains was 0.1 micron. |
