Abstract

A new double-sided silicon strip detector has been developed to study the phenomenon of ground-state proton radioactivity. Highly proton-rich fusion-evaporation reaction products are velocity and mass separated using the Daresbury recoil separator before being implanted into the strip detector located at the separator focal plane. The double-sided strip detector has 48 strips per face with a pitch of 335 μm. Front and back strips are orthogonal providing an effective pixel area of 0.09 mm , enabling correlations between implanted ions and subsequent decays to be clearly established. Test results obtained using the reactions Ni+ Mo→ Yb and Ni+ Fe→ Xe are reported. In the latter commisioning experiment the proton decay of I was unambiguously established using the correlated decay sequence I→ Te→ Sn.
