The collinear group SU(6)w enables us to discuss vertices, form factors and other collinear processes in an SU(6)-theory which is consistent with relativistic invariance. It leads, however, to a classification of the particles which is different from that of the “staticL SU(6)s. The general “W-spin” properties of an arbitrary spin state constructed from any number of basic spin i objects are di...

A method called "backprocessing", for subgross examination of sections, ranging between 50 microns and 1 mm in thickness using a dissecting microscope was developed.
