摘要：

Highly accurate results are presented for the susceptibility chi(T) of the s = 1/2 Heisenberg antiferromagnetic chain for all temperatures, using the Bethe ansatz and field theory methods. After going through a rounded peak, chi(T) approaches its asympotic zero-temperature value with infinite slope.
