DESCRIPTION:We study the intrinsic spin Hall effect (SHE) and \nanomalous 
 Hall effect (AHE) in transition metals. We argue \nthat (1) the intrinsic 
 mechanism can be understood as an \norbital Aharonov-Bohm effect and (2) t
 he origin of the \nSHE and AHE is the "orbital" Hall effect and\,  based o
 n \nit\, the magnitude and the sign of the SHE and AHE are \nsemiquantitat
 ively understood. The sign change of SHE with\nthe increase of the atomic 
 number predicted by the present\ntheory has recently been confirmed experi
 mentally\, implying\nthat the intrinsic mechanism indeed works in transiti
 on \nmetals.
