The coincidence nueasurenaent between the Conrpton scattered jchoton and the recoiled elec-tron (X, eX) provides direct infornaatiota on the three ditaaensional electron unotaaeratum density(3D-BIVID). A new coincidet'uce rtaeastrren?ent systeuaa, which gives us tlae energy spectruraa of therecoiled electron by tlae nae?tns of' titrme of flight tnethod, hats been successf'trlly develojced. Tlaeobtained monaentvrrn space resolution of' the 3D-E[MD XVdS 0.3021.11., and the feasibility of tnea-strring tlte state-selective 3D-EIVID has been denaonstr'ated by trsing an electron binding energyeffect. The 3D-EIVID of a graphite f'oil is cotaapared with a tlueoretic?tl band calctrlation, xvitlain apresent statistical acctrracy. The ef['ect of rntrltiple scarttering of recoiled electrons was calctrlatedby a Monte-Carlo sirntrlation and the experitnental data xvere couaupared with tluem.
