Abstract

In an experiment at the Recoil Mass Spectrometer at the Holifield Radioactive Ion Beam Facility, the very small α-decay branch of ¹⁰⁹I, b_α=(1.4±0.4)-10^-4, has been measured. The Q_α-value for this transition allowed for the determination of Q_p(₁₀₅Sb)=356±22 keV, about 130 keV lower than previously claimed. This difference increases the partial half-life for proton decay by several orders of magnitude, making the probability of observing direct proton decay of ¹⁰⁵Sb very small, much below any previous experimental limit. The results and consequences for the astrophysical rp-process are discussed.
