================================================================================
ADC_Keywords: Excitation rates ; Interstellar medium

Description:
  Theoretical rate constants amoung the lowest 45 para and 45 ortho rotational 
  levels of water in collision with He atoms have been calculated for 
  temperatures between 20 and 2000K using a recently improved theoretical
  interaction potential.
