$L_1$ part I understood. It is a nice trick to split the integration range. To my shame I do not see why it is integrable in $L_2$. Integral $\int 1/x^2 dx$ does not converge.

I ``cooked'' such distribution based on what I need. If you put your comment as an answer I will accept it. You gave a reference to the Stieljes measure which is nice.
