In a field emission tube with two probe-holes the cross-correlation functions of current fluctuations from potassium submonolayers on tungsten have been investigated. The measurements were carried out in the temperature range of 290-430 K and with coverages between 0.05 and 0.87. The experimental correlation curves were approximated by a sum of three exponential functions revealing three components with different time constants τi and amplitudes R. The temperature dependence of the amplitudes R2 and R3 is discussed in terms of collective ffip-flop processes. PACS numbers: 79.70.+q, 68.90. + g.
