| Abstract: | Special kinds of generalized superposition states, superposition coherent states, are studied in this paper. These states
can be produced by superposing a pair of coherent states |a〉 and |−a〉. Their quantum statistical properties, the fluctuations of field and squeezing have been discussed in detail. These properties
are dependent on superposition phase. We also describe the squeezing regions in phase space for these states. |

| Keywords: | superposition states even odd coherent state squeezing |
