The ion Sm3 has 5 electrons in the f-shell. Determine the orbital (L), spin (S) total (J) angular momentum quantum number for this ion. of this ion The Lande's g factor is given by tplt 0 K f a salt containing 1 g mole 3J(J 1)+S(S +1)-L(L +1) 2J(J+1) and the susceptibility is 3KT where the symbols carry their usual meaning.
Question 1 (8 marks in total) The deuteron is a bound state of a proton and a neutron. Treating nucleons as identical particles with spin and isospin degrees of freedom, the total state of the deuteron can be writ- ten space Ψ spin Ψ isospin. The deuteron has a total angular momentum quantum number J - 1 and a total spin S -1. Our goal is to determine the parity of the deuteron Q1-1 (1 mark) Show that the possible...
(c) Explain what is the significance of the magic numbers (N 2, 8, 20, 28, 50, 82 and 126). Explain how do the magic numbers depend on the spin-orbit term of the nuclear potential: Where the total angular momentum j is given by the sum of the orbital angular momentum i and the nucleon spin, 2 Derive the expression of Vor for j-1+and for j 7 marks]
