The relative widths for the proton (p) decay of the isobaric analog of the 208 Pb ground state have been remeasured with significantly improved accuracy using the charge-exchange reaction m Ph(p,n) rather than 201 Pb(p,p) and (p,p f ) excitation functions to populate the isobaric analog level. For the first time the sequential process ip,np) has been observed both with a heavy (A ~ 200) target nucleus and also with a target nucleus which is even-even rather than even-odd. The total cross section for the isobaric-analogstate reaction 208 Pb(£,?2) 208 Bi has also been measured for the range of proton bombarding energies between 25.2 and 47.3 MeV.
