摘要：
We report on recent inelastic neutron scattering (INS) measurements versus q in the highly one-dimensional compound N(i)(C2H8N2)2NO2 ClO4 (alias NENP). Our data allow a precise determination of the correlation length xi/d = 7 +/- 1. We present results concerning the excitations at q congruent-to 0.
