Using Bethe ansatz integral equations, we calculate the free energy and sus-ceptibility of spin-} one-dimensional Heisenberg ferromagnet X=J?(838,.. - IC,(./<0) at I>0.004lJl. We find that the free energy and susceptibility are expandedby V'7'/IJI at low temperature:c t IN'/' t IX' t r '.'l' t r x'xf="'I ""'!l./17 ""'KIJIJ "'1,?t?) "!l.Zl7 3/IJIX" l?Jl,X'/" /l./IN' /IJIN'/'1x=lJl- 0.166757) +0.5S1<,7) +0.68jy7 +0(-7-) j.tcThe first term of free energy coincides with the spin wave calculation. The firsttcrm of susceptibility coincides with Fisher's solution of classical Heisenberg Fer-romagnet. We conclude ct= -0.5 and 7=2.
