| Abstract: | A new method which is combined by the twospin cluster expansion with the discretized path-integral is employed in the study of the effect of a crystal field on the Ising model with mixed-spin in a weak transverse-field. The analytical expressions of the free energy and the critical transverse-field of the systems are obstained. The results are analysed and discussed in comparison with that of s=1 in this paper. |

| Keywords: | mixed-sipin two-spin cluster discretized path-integral critical transversefield. |
