“…138 Carlson, Schick, Talbert, and Wohn (26) reported the half-life of Cs to be 32.2 ^ 0.2 minutes, and Alvëger, Naumann, Retry, Sidenius, and Thomas (27) measured energies and intensities for nine gamma rays observed 138 in the Cs decay. Nagahara, Miyaji, Kurihara, Mizuno, and ishizuka (28) observed 3Î gamma-rays and placed them in a level scheme of 19 excited levels with the aid of Ge(Li)-Na1 (Tl) coincidence data. A list of these levels will be presented later.…”
