Strongly interacting selective adsorption resonances were examined for 4He/graphite at both 17 and 4.7 meV incident energies. Weak second-order resonances were seen by means of their admixture with stronger resonances. Matrix elements were measured at 4.7 meV and found to agree with those determined by Boato et al., at higher incident energies.
