(p,t) reaction on even-mass cadmium nuclei: Test for the admixture of intruder configurations in the ground states

The ${}_{}{}^{106}{}_{}{}^{}$,108,110,112,11 ${}_{}{}^4{}_{}{}^{}$,116Cd(p,t) reactions have been investigated at $E_{\mathrm{p}=26\mathrm{}}$ MeV. Enhancement factors for the ground-state to ground-state transitions have been extracted and compared with predictions for two-nucleon transfer strengths. No evidence for a sizable admixture of the intruder configurations in the ground states is deduced from this experiment.
