Towards digital spectroscopy of proton emitters
First observations of fine structure in proton emission from the isotopes 145Tm and 1446m,gsTm are reported. The 3 μs decay of 145Tm was studied by means of the Recoil Mass Separator and digital processing of its detector signals. The structure of the proton-emitting states as well as the properties of daughter states, a 2+ state in 144Er and the S1/2 and h11/2 neutron levels in 145Er, are deduced.
