Abstract：
The variations in moments of inertia (J⁽²⁾ and J⁽¹⁾) with rotational frequency for the series of yrast SD bands in even-even nuclei, ^192—198Pb(1) and ¹⁹⁸Po(1), are investigated by using the particle-number conserving method for treating the pairing interaction (monopole and quadrupole). The observed co variations of J⁽²⁾ and J⁽¹⁾ are reproduced quite well in the PNC calculation, particularly the microscopic mechanism (the contributions from each major shell and each cranked Nilsson orbital) is clearly displayed. It is found that the smooth rise of J⁽²⁾ with ω is attributed to the contribution from the intruder shells (neutron N=7 and proton N=6).
