Angular Correlation of Gamma Rays in the Decay ofRb84

Angular-correlation measurements have been made of the cascade gamma rays following the beta decay of ${\mathrm{Rb}}^{84}$. The results show that the spin and parity of the second excited state of ${\mathrm{Kr}}^{84}$ is 2+. The energies of the gamma rays in this decay have also been remeasured using a lithium-drifted germanium detector and are 883, 1018, and 1901 keV with errors of ±2 keV and relative intensities of 100:0.53:1.06, respectively.
