Signals of the appearance of the shears mechanism, such as smooth decreases of the shears angle and of the $B$(M1)/$B$(E2) ratio with keeping the nearly constant tilt angle, are well reproduced. Thus it is shown that the microscopic RMF model can nicely describe the shears band in this nucleus.5 pages, 6 eps figures included, uses REVTeX and epsf.sty, to appear in Phys. Rev.
