Abstract / Description of output

The Daresbury recoil separator has been used to measure proton radioactivity from the nuclei Lu150, Lu151, and Tm147, produced using the reactions Ni58+96Ru→154Hf* and Ni58+92Mo→150Yb*. The half-life of Lu150 has been measured for the first time as 35±10 ms, which identifies the proton decay as an l=5 transition from the h11/2 proton state. New half-life and energy measurements have been made for the known proton transitions from Tm147 and Lu151, which have been unambiguously assigned using the direct mass identification of the recoil separator. A new half-life measurement of the proton emitter I109 is also reported.
