摘要：

The structure of liquid Bi-Ga alloys has been examined by neutron scattering measurements. The structure factors of this system have been obtained along the liquidus curve and also at higher temperatures above the critical temperature where the miscibility gap closes. A remarkable change in the structure factor has been observed at around 70 at.%Ga, which composition corresponds to the maximum temperature in the curve where miscibility gap closes. This concentration variation of the observed structure factors has been discussed in view point of the thermodynamic properties.
