I'm working on modelling a system that include a gaussian low pass
filter on litterature on the net i can find information about the waveform
of the filter but i can't find nothing about the formulas to determine
the L,C and R values. Does someone can help me or knows a website with
this information ?

If you need a design of a filter, there is a program
on the website:http://tonnesoftware.com/. called ELSIE. You can put
in your parameters ( stop band, passband etc) and it will spit out the
values for the filter.

After reading of your
need for the Gaussian prototype values, I did a search for them and
could not locate tables for the Gaussian filter. So, I used a filter
design program and set the frequency for 1/(2*pi) and the source/load
terminations for 1 ohm and came up with a table of values for order
3 through 10. If you still need them, you can find them here:

While I was at it, I updated the Chebyshev tables to include even-order
filter values. A lot of tables only supply odd-order values, because
the insertion loss of a Chebyshev at DC (0 Hz) is equal to the ripple
value rather than 0 dB.
