The decay of $sup 44$K, $sup 44$Sc/subg/, and $sup 44$Sc/subm/ to levels of $sup 44$Ca have been studied. For decay of $sup 44$K, approximately 125 $gamma$ rays have been observed using singlet, Compton-suppression, and $gamma$- $gamma$-coincidence Ge(Li) spectroscopy. The decay data, used in conjunction with recent reaction spectroscopy data, have led to the identification of 35 levels in $sup 44$Ca that are populated in $beta$ decay. The levels below 4500 keV are discussed within the framework of multiple vibrations. The levels at (J/ sup pi/ in parenthesis) 3661.53 (1$sup -$), 3676.07 (2$sup -$), 3711.80 (4$sup - $), 3913.8 (5$sup -$), and 4358.42 keV (3$sup -$) are suggested as the two phonon quadrupole-octupole pentad.
