利用勒让德函数展开式，从局部二体势矩阵元形式的准粒子散射振幅模型出发，得到了液体/SUP3/He的输运系数和超流体Ginzburg-Landau参数的解析结果。我们对测量的朗道参数和输运系数进行了最小二乘拟合，并对包含勒让德分量的模型与L或=3进行了近乎完美的一致。
Using a Legendre function expansion, we obtain analytic results for the transport coefficients and superfluid Ginzburg-Landau parameters of liquid /sup 3/He from any model quasiparticle scattering amplitude with the form of a matrix element of a local two-body potential. We perform a least-squares fit to the measured Landau parameters and transport coefficients and obtain nearly perfect agreement for models including Legendre components with l< or =3.
