摘要

The excited states of the 72Ge nucleus were investigated in radioactive decay of 72 As. Three new transitions with 1996.58, 2125.59 and 2255.49KeV have been of found for the first time. One λ-ray with 912.09keV has been placed in the decay scheme for the first time, and the placement of 1938.88, 2116.79, 2785.59, 2833.03,1950.69 and 3338.00keVλ-rays are confirmed again in the present work. One new level at 2027.72kev excitation energy is proposed. The level scheme was established and for a number of levels spin-parity assignments are suggested on the basis of logft values and λ-branching ratics.
