The spin-orbit interaction in an sodium atom is given by H =

The spin-orbit interaction in an sodium atom is given by H = 21.5, where I and 5 denote the orbital and spin angular momenta of the electron, respectively. The splitting between the levels P3/2 and P2 (due to spin-orbit inter- action) is (Take fi = 1)_ units (Your answer should be an integer)
