  helium release
It is shown that the alloying elements do not have a unique effect on the mechanisms of helium release from bcc and fcc alloys.
      
For samples which were irradiated with helium ions to high doses, a massive helium release was also observed.
      
Thermal charging with deuterium was found to reduce the helium self-trapping energy as was expressed by lower temperature helium release.
      
Thus it is presently unclear whether isotopic mass fractionation does or does not accompany helium release from apatite in all cases.
      


The release behavior of 3He and other impure gases from titanium tritide films were analyzed by a quadrupole mass spectrometer(QMS) in an ultravacuum metal system with a limit vacuum of Z×10-7Pa. The 3He release fraction for two titanium tritide samples with initial atomic ratio of 1.68 and 1.69 were measured in a period of 410 days. It was shown that the release fraction of the two samples was maintained in 10-5 level when the 3He concentration in samples reachs to 0.1, and the release fraction was increased...

The release behavior of 3He and other impure gases from titanium tritide films were analyzed by a quadrupole mass spectrometer(QMS) in an ultravacuum metal system with a limit vacuum of Z×10-7Pa. The 3He release fraction for two titanium tritide samples with initial atomic ratio of 1.68 and 1.69 were measured in a period of 410 days. It was shown that the release fraction of the two samples was maintained in 10-5 level when the 3He concentration in samples reachs to 0.1, and the release fraction was increased 5-10 times by vibration. Analysis of impurity release from titanium tritide film shows that samples, prepared in a glass vacuum system would be polluted by oil. The mechAnism of early 3He release from titanium tritide was also discussed in this paper.

在极限真空为2×10-7Pa的超高真空全金属系统中,用四极质谱计分析了氚钛膜中释放的3He气体及其它杂质气体组分。对两块原子比分别为1.68和1.69的氚钛膜中释放的3He经过长达410d的测量.结果表明,当样品中3He浓度达到0.1时,3H3的释放系数仍保持为10-5量级。振动使氦的释放系数增大了5—10倍。对氚钛膜中释放的杂质气体组分的研究结果表明,用玻璃真空系统制备的氚化钛样品被油污染比较严重。对氚钛膜中3He的早期释放机理也进行了探讨。
