Charge density difference in ( 1¯10 ) plane: (a) system with single Re in γ phase; (b) system with NN Re–Re system; (c) NNN Re–Re system; (d) Re cluster system. The four systems correspond to the four systems S8, A4, B6, C5 in Fig. 2. The contour lines denote charge accumulation (solid line) and depletion (dashed line) and are plotted with an increment of 0.0027 e/a.u.3
