Energy Levels inNa21

The ${\mathrm{Na}}^{21}$ nucleus has been studied through two reactions: the ${\mathrm{Ne}}^{20}(d, n){\mathrm{Na}}^{21}$ reaction using a fast neutron spectrometer, and the ${\mathrm{Ne}}^{20}(p, \gamma ){\mathrm{Na}}^{21}$ reaction using both single-crystal and Hoogenboom techniques. ${\overline{E}}_d$ for the neutron spectroscopy for the major part of the work was centered about 4.87 Mev, while the capturing resonance for the gamma-ray work was at ${\overline{E}}_p=1.17\mathrm{}$ Mev. Enriched neon was employed as target gas.
