The decay of Sr-83 has been reinvestigated using gamma singles and gamma-ga
mma-t coincidence measurement The number of gamma transitions assigned to 8
3Sr decay has been expanded from 102 to 196.19 new levels of Rb-83, added t
o the old level scheme and 8 formerly adopted levels are denied by the pres
ent study. New data of branching ratio, log ft value and spin-parity are al
so obtained.
