Age and chemical composition of the globular cluster NGC 6652
  We present the results of determination of the age, helium mass fraction (Y),
metallicity ([Fe/H]), and abundances of the elements C, N, O, Na, Mg, Ca, Ti, C
and Mn for the Galactic globular cluster NGC 6652. We use its medium-resolution
integrated-light spectrum from the library of Schiavon and our population
synthesis method to fulfill this task. We select the evolutionary isochrone and
stellar mass function for our analysis, which provide the best approximation to
the shapes and intensities of the observed Balmer line profiles. The determined
elemental abundances, age and metallicity are characteristic of stellar
populations in the Galactic Bulge.
