      Dear Peter.
      Thank you very much for your answer. Approximately
I had made PMTs in the same way, as you said.

      Much more difficult for me to imply the model of reflection 
from PMT photocathod surface - the reflection coefficent from the 
thin metalic film has the angular dependance (see the NIM article,
cited in first letter).
      In Borexino neutrino detetector and in LENS project for
detection of solar neutrinos exactly the same PMTs, as in the 
NIM article, are used. 
      As far as I know, one member of LENS project had already 
made this model for complex reflection, but unfortunately in 
old geant3 fortran packet.
