Abstract

By laser ablating the pure B and P powders and their mixture, abundant Bn?Pn?and BnPm?cluster ions were produced and recorded subsequently by the time-of-flight mass spectrometers. Almost all Bn?observed in this experiment have a similar structure, which is believed to be the close packed structure. The magic no. for Pn?is 8, which is 1 of their structural units. It is possible that some Pn? as well as some BnPm?cluster ions, may have a ring structure. All Pn?Bn?cluster ions have a strong tendency to have their electrons paired.
