Then I have a "stupid question", can we replace B3+ with He with the
same number of electrons ?
Not at all! He has a much lower nuclear charge than B, so the electron
cloud of B will be much more dense at low(er) distances from the
nucleus. The corresponding atomic form factors will then decay at
markedly distinct rates with q!
