Weakly interacting, massive particles (WIMPs) have recently been proposed as a solution to the solar neutrino problem1-3. Whereas standard solar models consistently predict a detection rate of (high-energy) neutrinos 3 times higher than that observed in the Davis experiment4-6, the presence of hypothetical massive particles in the solar centre would resolve this discrepancy. Models which incorporate a relative number of 10-11 WIMPs with appropriate scattering cross-section would reduce the predicted neutrino detections by 37Cl to the observed value, without significant changes in the solar structure outside the central region 1-3. We have subjected these models to an observational test of p-mode oscillation frequencies by computing frequency differences of low-degree, high-order oscillation frequencies. Although standard solar models also pass this test, WIMP models provide a better fit.
