摘要：

We investigate the critical exponents eta(3)(alpha, M) and eta(1)(alpha, M) associated with the singularities in the longitudinal and transverse structure factors of the one-dimensional antiferromagnetic Heisenberg model with nearest-(J(1)-) and next-nearest-(J(2)-) neighbour coupling of relative strength alpha = J(2)/J(1) and an external field B with magnetization M(B).
