The Daresbury recoil separator has been used to measure proton radioactivity from the nuclei [sup 150]Lu, [sup 151]Lu, and [sup 147]Tm, produced using the reactions [sup 58]Ni+[sup 96]Ru[r arrow][sup 154]Hf[sup *] and [sup 58]Ni+[sup 92]Mo[r arrow][sup 150]Yb[sup *]. The half-life of [sup 150]Lu has been measured for the first time as 35[plus minus]10 ms, which identifies the proton decay as an [ital l]=5 transition from the [ital h][sub 11/2] proton state. New half-life and energy measurements have been made for the known proton transitions from [sup 147]Tm and [sup 151]Lu, which have been unambiguously assigned using the direct mass identification of the recoil separator. A new half-life measurement of the proton emitter [sup 109]I is also reported.
