Abstract: Radiations from Zn⁶⁵ have been studied by means of a thin lens beta ray spectrometer. A spiral baffle was used to separate positrons from negatrons. The gamma ray spectrum in the energy range above 100 kev was found to consist of one gamma ray at 1.11 mev and annihilation radiation at 0.51 mev. One positron group was found with maximum energy at 0.327 mev. No internal conversion electrons were found. A decay scheme has been proposed in which Zn⁶⁵ decays either by K-capture to a 1.11 mev excited state of Cu⁶⁵ or bypositron emission to the ground state of Cu⁶⁵.
