Several experiments were performed at the UNISOR isotope separator facility at HHIRF at the Oak Ridge National Laboratory on the [beta][sup +]/EC decay of neutron-deficient rare earth isotopes. Data for the three decay chains [sup 137]Eu [yields] [sup 137]Sm [yields] [sup 137]Pm [yields] [sup 137]Nd, [sup 135]Sm [yields] [sup 135]Pm [yields] [sup 135]Nd and [sup 133]Sm [yields] [sup 133]Pm [yields] [sup 133]Nd were obtained consisting of multiscaled spectra of [gamma] rays, x rays, and conversion electrons, as well as [gamma][gamma]t, X[gamma]t, e[gamma]t and eXt coincidences. Gamma rays associated with the decay of [sup 133]Sm and [sup 133]Pm were observed for the first time. The decay of a new low-spin (1/2,3/2) isomeric state, with a half life around 70 sec was seen in [sup 133]Nd. Systematics and particle-rotor calculations are discussed.
