Alpha and Gamma Spectra ofCf246

The alpha and gamma spectra of ${\mathrm{Cf}}^{246}$ have been studied with an alpha-particle spectrograph and gamma-ray scintillation spectrometer. Alpha groups of 6.753 Mev (78 percent) and 6.711 Mev (22 percent) were observed. $L$ x-rays and gamma rays of ∼100 kev (1.4×${10}^{-2\mathrm{}}$ percent) and ∼44 kev were assigned to ${\mathrm{Cf}}^{246}$. These results are evaluated with respect to the developing theory and systematics of complex alpha spectra and excited states of even-even nuclei.
