英文摘要	We present chemical abundances of 15 stars in the gamma Leo moving group based on high-resolution spectra with the Subaru High Dispersion Spectrograph. The sample was picked up by applying wavelet transform to UVW velocity components of stars in the solar neighborhood. Both photometric and spectroscopic method have been used to determine the stellar parameters of stars. Abundances of 11 elements including Na, Mg, Al, Si, Ca, Ti, Cr, Fe, Ni, Y, and Ba are measured. Our results show that the member stars display a wide metallicity distribution with abundance ratios similar to Milky Way disk stars. We presume that the gamma Leo moving group originated from dynamical effects that are probably related to the Galactic spiral arms.
