Negative power supply

[electros6]

I tried to do dual power supply. The positive part works fine but the negative part is oscillating. I have attached the basic schematics .  I don't have digital scope so I have drawn the output that I have scene in my analog scope . Please guide

QWhat a strange circuit.

It oscillates because the phase shift is 180 at a frequency when the gain is above one so negative feedback becomes positive feedback. Add a compensation capacitor into the feedback loop to reduce the high frequency gain so the gain with 180 degree phase shift is under 1.
