Abstract:
    We have experimentally studied the excitation of the rhenium atom 
    by collisions with slow monoenergetic electrons and measured 47
    excitational cross sections for lines of ReI (Z=75) at an electron 
    energy of 50eV.

  76- 81  F6.3   ---      Ilam/gA    ? Ratio I*Lambda/g*A (1)

Note (1): Ratio I*λ/g*A, where
    I is the line intensity,
    Lambda is the  line wavelength,
    g is the statistical weight of upper level and
    A is the transition probability
    and should be the same for each set of lines with a common upper level.
