Fine Structure in Proton Emission from the Deformed 141g.sHo and 141mHo

Fine structure in proton emission from the deformed states {sup 141g.s}Ho (T{sub 1/2} = 4.1 ms) and {sup 141}mHo (T{sub 1/2} = 7.4 {micro}s) has been discovered at Oak Ridge by detecting fusion evaporation residues with the Recoil Mass Spectrometer, Si-detectors and digital signal processing electronics. The branching ratios to the first 2{sup +} excited state in {sup 140}Dy were measured to be I{sub p}{sup g.s.}(2{sup +}) = 0.9{+-}0.1% and I{sub p}{sup m}(2{sup +}) = 1.7{+-}0.5%. A comparison of the available calculations to the experimental values calls for further development of the theoretical models.
