const G4int LSO_NUMENTRIES_1 = 1;

This must be at least 2!

The G4MaterialPropertyVector is implemented as a G4std::vector, with the sorting operation defined as MPVEntry1 < MPVEntry2 == photon_momentum1 < photon_momentum2. This results in all G4MaterialPropertyVectors being sorted in ascending order of photon momenta.

If you want a very narrow line you can set:

LSO_FEST_Energy[2] = {2.95167*eV, 2.95169*eV}

There should be a natural line width >0 anyway.

Also, although I don't think it matters, I suggest to arrange the array with increasing energy:

{1.84*eV, 4.08*eV}
