NucleargFactor of the First Excited State inV51

Abstract

The angular distribution of the resonance radiation from the 320-keV state in ${\mathrm{V}}^{51}$ has been measured using gaseous ${\mathrm{Cr}}^{51}$ ${\mathrm{Cl}}_2$ ${\mathrm{O}}_2$ as the source of resonant gamma rays. The distribution can be described by $W\left(\theta \right)=1+(0.44\mathrm{}\pm 0.03)P_2\left(cos\theta \right)$, corresponding to a mixing amplitude $\delta =+0.43\mathrm{}\pm 0.03$.
