摘要：

The melting curves of He and Ne were measured up to 80 and 70 GPa, respectively, significantly extending the pressure range of previous measurements. Melting was detected in situ by the laser speckle method using the laser-heated diamond-anvil cell. Temperatures were measured in the visible as well as infrared range. Our He melting curve differs considerably from earlier experimental data above 30 GPa. The present Ne melting curve does not agree with the predictions from corresponding states theory in the range from 15 to 70 GPa.
