英文摘要	We study the structure of isomeric state 21(+) in the odd-odd N=Z nucleus Ag-94 using a shell model, which is capable of describing the spectra of upper g(9/2)-shell nuclei close to the N=Z line. It is shown that the 21(+) state becomes isomeric because of level inversion of the 19(+) and 21(+) states due to core excitations across the N=Z=50 shell gap. Calculation of spectroscopic quadrupole moment indicates clearly an enhancement in these states due to the core excitations. In the present shell model calculation, however, the large-deformation picture of Mukha et al. in Nature 439, 298 (2006) cannot be accepted.
