摘要翻译:
采用一种新的发散级数求和方法,可以显著提高由场理论重整化群确定临界指数的精度。液氦中λ相变的指数nu=0.6700pm0.0006与实验结果吻合较好,但与基于高温级数、Monte Carlo方法和合成的理论结果相矛盾。

英文摘要:
The use of a new method for summing divergent series makes it possible to significantly increase the accuracy of determining the critical exponents from the field theoretical renormalization group. The exponent value \nu=0.6700\pm 0.0006 for the \lambda-transition in liquid helium is in good agreement with the experiment, but contradicts the last theoretical results based on using high-temperature series, the Monte Carlo method, and their synthesis.
