Abstract

ones. The computed evaporation energy trends rationalize experimentally observed ion-yield anomalies and delineate where semiclassical Feynman-Hibbs corrections deviate from exact ground-state sampling. Overall, this work establishes a benchmark quantum description for protonated He clusters and offers microscopic insight into the interplay of nuclear quantum effects, many-body interactions, and isotopic substitution in He-solvated ionic complexes, with implications for ion spectroscopy and low-temperature cluster physics.
