Abstract
Gamma rays and conversion electrons emitted in the 117Cs and 117Xe decays have been studied from on-line mass-separated 117Cs sources at the ISOLDE facility. A new 117Xe decay scheme has been constructed and a level scheme has been established for the 117Cs decay. The results are discussed in the framework of the recent understanding of the odd-mass neutron-deficient I and Xe systematics.
