We obtained a high resolution, high signal-to-noise UV-blue spectrum of theextremely metal-poor red giant HD88609 to determine the abundances of heavyelements. Nineteen neutron-capture elements are detected in the spectrum. Ouranalysis revealed that this object has large excesses of light neutron-captureelements while heavy neutron-capture elements are deficient. The abundancepattern shows a continuously decreasing trend, as a function of atomic number,from Sr to Yb, which is quite different from those in stars with excesses ofr-process elements. Such an abundance pattern is very similar to that ofHD122563 that was studied by our previous work. The results indicate that theabundance pattern found in the two stars could represent the pattern producedby the nucleosynthesis process that provided light neutron-capture elements inthe very early Galaxy.
