Ionic products were detected by the time of flight mass spectrometer A series of protonated cluster ions were measured:(C_2H_5OH)_nH~+ and(C_2H_5OH)_n(H_2O)_mH~+(n=1-12,m=1-4),which were produced from the proton transfer reactions in the clusters.

• 实验观测到多个序列的质子化团簇离子:(C2H5OH)nH+和(C2H5OH)n(H2O)mH+(n=1-12,m=1-4),其产生是通过团簇内的质子转移反应。
