Abstract Experimental and theoretical study of the β − decay of 100 Nb to the two-quasiparticle states in 100 Mo suggests the opening of the Z =40 subshell gap in the proton pf-0g 9/2 shell for isobars near 100 Mo. Assuming the opening of the Z =40 subshell gap both for 100 Mo and 100 Ru enables the study of the effects of this subshell gap upon the two-neutrino and neutrinoless double-beta-decay rates of 100 Mo to the ground state and excited states in 100 Ru. It is found that the influence of the opening of the Z =40 gap has very minor effects on the beta-decay and double-beta-decay feeding of the 0 + and 2 + states of 100 Ru.
