[en] In reactions with light incident charged particles at energies below the Coulomb barrier, a correlation is found between the energy dependence of the isomeric ratio and the magnitude of the mean angular momentum. For energies far below the Coulomb barrier, a weak dependence of the isomeric ratio and of the mean angular momentum of the collision energy is obtained. The ¹⁸⁴Re and ^196,198Au nuclei, which have markedly different spins of the ground and isomeric states were chosen for this study. The yields were measured for the reactions ¹⁸¹Ta(α,n)^184m,gRe, ¹⁹³Ir(α,n)^196m,gAu, ¹⁸⁴W(p,n)^184m,gRe, ¹⁹⁸Pt(d,2n)^198m,gAu, and ¹⁹⁷Au(d,p)^198m,gAu. 11 refs., 2 figs., 1 tab
