First observation of the beta decay of117Pd and the discovery of a new isotope119Pd

Abstract

In this paper we wish to report the first direct observations of the beta decays of117Pd and of a new isotope119Pd. The measuredβ-half-life is 4.3±0.3 s for117Pd. For119Pd, the existence of two beta-decaying states with the same half-life but of opposite parity cannot be excluded. The measured half-life for119Pd is 0.92±0.13 s. The observed beta half-lifes are in good agreement with the QRPA predictions. The observed level structure of117Ag and119Ag are discussed in the frame of the level systematics of the known odd Ag isotopes closer to stability.
