joy o joy, at last I have found the unit step response.
The problem was with the inverse laplace transform. Instead of the amplitude of the sine being 1, it depends on the damping factor = df/sqrt (1-(df*df)).
I would like to take the special case were R=0 i.e. the roots are complex. Your patience and assistance is always welcome.
Kind regards, Derek
