Singular Attraction
Let the interaction potential have a singularity at r D a resembling the potential of
image force. Figures 3.15 and 3.16 show schematically the situation in this case.
When energy E is positive, function L 2 .r/ has a minimum at r D r
located at
r>aand L a D L 2 .r /.Atnegative E (see Fig. 3.16 )
L a D min L 2 .r /;L 2 .R/
where r
is the solution to the equation
L.r / D L a D min .L.r//; r a:
