Rocío Rodríguez-Cantano, Tomás González-Lezana, Pablo Villarreal, David López-Durán, Franco A. Gianturco, and Gerardo Delgado-Barrio investigate the precise location of Ca impurities in He using path integral Monte Carlo calculations for clusters with up to 40 He atoms. On page 1318 (DOI: 10.1002/qua.24622), they show the structure and energetics of the droplets depends on the He–Ca interaction used. By comparing theoretical results with existing experimental data, this study of He–Ca potentials highlights the importance of a correct description of the impurity-dopant interaction.
