Sequential growth simulation of (NH3)n clusters (n = 2-8) in ultracold superfluid environment

►Sequential growth of ammonia clusters in He droplets. ► Formation probability for different isomeric species. ► Cyclic structures dominate the population of trimer, tetramer and pentamer. ► Larger clusters are mainly built by fused tetramer rings. ► Ammonia clusters present higher insertion probabilities than water ones.
