Abstract

The critical Coulomb explosion number, i.e., the lower bounds of particle size required to stabilize a multiply charged alkali halide cluster against Coulomb explosion were calculated using a simple Coulomb potential. The magnitude of the charge ranges from 2 to 10. The influence of sign and position of the charges were assessed . The critical Coulomb explosion number increases with increasing number of charges on the clusters. The critical coulomb explosion number and the charge of the clusters are linearly related with a good correlation . The binding energies of the most tightly bound neutral isomers of (NaCl) n, n=2- 12, were calculated using a simple Coulomb potential. The stability order of the various isomers of a given cluster size is predicted using binding energy as a criteria. These results are compared with other works which employ refined but computationally expensive potential models . The agreement is good
