✦ Synopsis
Kcv~scd manoscnpr rccclvcd 18 hldrch 1977 'rflc cla~~c mcohcrcnt strwturc tunctwn (I.ISk), no(Q), IS dcrivcd for specific cxpcrimcntal orientation\ of the mamcnturn trmsfcr vector, Q, with rcspat to the ncm.itlc dlrcctoi, n. of an ahgncd "monocrysta~' mcsophasc. The partlculer umaw.11 model first consrdcrcd 15 that m which the mitral probahrlity component of the orIentationa correlation fun&Ion departs from uniformity to become a peaked function. The dndlytical EIW for Qlln is derived on the bais of Ihc mlcroscoplc scattering cpmmctry .md an cffcctwcly \tatlc princlpnl axa Brxf cxplxlt consideration is gven to the LISF tor the more gcncral "dynamic principal a~" model with spcc~fic Q to n cxpcrimcnhl contiguratlon. An altcrnatwc closed form IS given for Sk(a'), the dynamtcal cquw;knt of an order paramctcr.
