The fragmentation of Arn+He1000 (n=3,5) is investigated by zero-point averaged dynamics (ZPAD) and compared with recent results on Ar4+He1000 to investigate the influence dopant size. At core ZPAD, effective He-He potentials converged for He1000 ArnHe1000 are found alike which suggests that ZPAD simulations argon-doped helium nanodroplets (HNDs) could restrict obtained pure HNDs. clusters share a number similarities, like absence Ar+-containing fragments, occurrence ion ejections trappings, Arn+ electronic relaxation typically extending picosecond time scale, or primary events not necessarily representative final distribution fragments. However, Ar3+He1000 also exhibit unexpected behaviors an inefficient when starts uppermost Ar3+ state makes trapped within droplet.
