Question 6.

The ground state of deuteron is taken as an admixture of s and d states. The expression for the electric quadruple moment of the deuteron contains a cross term in s and d states because
(1) The nuclear force is short-ranged
(2) The nuclear force has a spin dependence
(3) The quadrupole operator has a terms of the form Y2m(θ, ϕ )
(4) The nuclear force has an exchange character

Question 7.

Deuteron has only one bound state with spin parity 1+, isospin 0 and electric quadrupole moment 0.286 cm2. These data suggest that the nuclear forces are having:
(1) only spin and isospin dependence
(2) no spin dependence and no tensor components
(3) spin dependence but no tensor components
(4) spin dependence along with tensor components
