However, the nature of the polluter(s) responsible for this phenomenon is still debated. The study of heavy elements and their relation to light ones can provide further constraints. In particular, we aim to explore the possible contribution of asymptotic giant branch stars of different stellar masses to the internal pollution in the cluster. We derive abundances of elements from different nucleosynthetic chains, such as Na, Mg, Ca, Sc, Cu, Y, and Ba. We did not find clear relations between the light s-process elements (represented by Y II) or heavy ones (represented by Ba II) with light elements (Li, Na, or Al). This indicates that the polluter(s) responsible for the Na (Al) or Li production does not produce large amounts of Y II and Ba II. Furthermore, the comparison with models discards a possible significant contribution to the cluster pollution from AGB stars with masses lower than 5 M_{Sun}_. In addition, we found a potential CH star in our sample.2023MNRAS.520.5938Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/520/5938CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/791/39 : NGC 6218 and NGC 5904 lithium abundances (D'Orazi+, 2014)J/ApJ/750/L14 : Abundances of red giants in NGC 6752 (Carretta+, 2012)J/A+A/567/A72 : Stellar parameters and abundances in NGC 6752J/A+A/533/A69 : Spectroscopy of 124 RGB stars in NGC 1851 (Carretta+, 2011)J/MNRAS/511/231 : Lithium study with GC NGC 6752 (Schiappacasse-Ulloa+, 2022)J/A+A/505/117 : Abundances of red giants in 15 globular clustersJ/A+A/505/139 : Abundances of red giants in 17 globular clustersJ/A+A/464/927 : Abundances of red giants in NGC 6752 (Carretta+, 2007)J/MNRAS/449/4038 : Li abundance of giants in 3 globular clustersJ/MNRAS/412/81 : Lithium abundance in M4 red giants (Mucciarelli+, 2011)J/A+A/350/955 : Atmospheric parameters in metal-poor stars.
