Berry's phase for a whole turn in a conical rotation of the magnetic field with a semiangle {theta} has been clearly manifested free from the dynamical phase shift using the magnetic-field-insensitive two-photon transitions between sodium-ground hyperfine states having different signs of the g factors. The solid angles for states with a positive g factor and with a negative g factor are verified to be 2{pi}(1-cos{theta}) and -2{pi}(1+cos{theta}), respectively, for a right-handed rotation of a magnetic field and a semiangle of 0{<=}{theta}{<=}{pi}/2.
