Magnetic Moment of the Second Excited State ofF19

The magnetic moment of the second excited state (200 kev) of ${\mathrm{F}}^{19}$ was deduced from the change, caused by a magnetic field, in the angular distribution of the de-excitation radiation following ($p, p^{\prime }$) by ${\mathrm{F}}^{19}$. The Larmor precession of the excited nucleus displayed in the angular distribution and the rotational change of the angular distribution was measured as a function of the magnetic field strength. If one disregards the influences of the surrounding atoms, the apparent value of the magnetic moment was deduced as $\mu ({\mathrm{F}}^{19*}, \frac{5}{2^{+}})=+(3.0\mathrm{}\pm 0.7){\mu }_N$. If one considers these effects, the value obtained gives a lower limit.
