Differential cross sections for the S34(p,n)34Cl reaction were measured at Ep=35 MeV. Remarkable differences were observed among the angular distribution shapes for the known 1+ states in Cl34 at 0.441, 0.666, 2.581, and 3.128 MeV. Distorted-wave Born approximation calculations using the recent full sd-shell wave functions of Brown and Wildenthal successfully reproduce such differences, whose origin was traced back to the different contributions of the J(LS)=1(0,1) and 1(2,1) transition amplitudes. The 1+ transitions with dominant 1(0,1) amplitudes required a renormalization factor N of about 0.8, which agrees well with that obtained for the + decay of Ar34. The 1+ and 2+ transitions with dominant 1(2,1) and 2(2,1) amplitudes required N of about 0.5. Similar distorted-wave Born approximation calculations gave a good description of the S=0 and L=0 and 2 transitions without any renormalization.
