Description

Highly accurate results are presented for the susceptibility, $��(T)$ 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, $��(T)$ approaches its asympotic zero-temperature value with infinite slope.
