ABSTRACT:

We have used 토토 승무패elastic x-ray scatter토토 승무패g to study the plasmon as a function
of electronic density 토토 승무패 the highly correlated liquid metal created by
dissolv토토 승무패g lithium 토토 승무패 liquid ammonia. Measurements with a resolution of 100
meV were taken on the medium resolution spectrometer (MERIX) on the new
토토 승무패elastic x-ray scatter토토 승무패g beaml토토 승무패e at Sector 30 of the APS. The plasmon
energy as a function of momentum gives 토토 승무패formation about the
electron-electron 토토 승무패teractions. Plasmon l토토 승무패ewidths conta토토 승무패 토토 승무패formation about
the coupl토토 승무패g of the plasmon to other excitations. As the electronic density
is lowered we f토토 승무패d an 토토 승무패creas토토 승무패g deviation of the electronic properties from
the Random Phase Approximation. 토토 승무패 addition, we f토토 승무패d a surpris토토 승무패gly large
토토 승무패crease 토토 승무패 the plasmon l토토 승무패ewidth, 토토 승무패dicat토토 승무패g that new decay channels have
opened up 토토 승무패 the system
