An investigation of the decay scheme of K44 has been made with anthracene- and 5″×5″ NaI(Tl)-scintillation counters, and coincidence techniques. In addition to the 4.91-, 3.55- and 2.63-MeV beta rays, the following gamma rays has been assigned to Ca44: 0.48-, 0.63-, 0.74-, 0.90-, 1.06-, 1.16-, 1.5-, 1.74-, 2.08-, 2.17-, 3.4-, 4.4-, 4.6- and 5.0-MeV. A decay scheme is proposed.
