我们广泛地研究了自旋极化的氚原子系统的静态和动态性质。特别地，我们计算了二体|F，m(F)>；=|0，0>；S波的散射长度，表明在约870G的场强下，它可以通过费什巴赫共振来操纵，这样的共振可能被用来制造和控制处于|0，0>；态的玻色-爱因斯坦氚凝聚体。进一步证明了四重氚三聚体是唯一的束缚氢同位素，它的单振动束缚态是Borromean态。给出了较大自旋极化的氚团簇的基态性质，并与氦团簇的基态性质进行了比较。
We present an extensive study of the static and dynamic properties of systems of spin-polarized tritium atoms. In particular, we calculate the two-body |F,m(F)>=|0,0> s-wave scattering length and show that it can be manipulated via a Feshbach resonance at a field strength of about 870 G. Such a resonance might be exploited to make and control a Bose-Einstein condensate of tritium in the |0,0> state. It is further shown that the quartet tritium trimer is the only bound hydrogen isotope and that its single vibrational bound state is a Borromean state. The ground state properties of larger spin-polarized tritium clusters are also presented and compared with those of helium clusters.
