Abstract Proton holes states have been studied up toE x=17 MeV andE x=3.5 MeV in the119In nucleus via the120Sn(d,3He)119In reaction respectively atE d=108.4 MeV andE d=51 MeV. DWBA analysis of angular distributions has allowedl attributions for a large number of new levels and the determination of valence and inner hole strength distributions. The first 1g 9/2, 2p 1/2 and 2p 3/2 levels only exhaust 40%, 60% and 32% of their respective sum rule limits. The missing strengths are shared among several low lying levels and significant higher lying contributions. The 1f strength, not identified in the previous experiments is spread fromE x=1 MeV to about 17 MeV. The low lying levels aroundE x=2.4 MeV could exhaust some 40% of the 1f 5/2 sum rule. The higher lying strength with a flat maximum aroundE x=7.5 MeV could account for the 1f 7/2inner hole strength and the missing 1f 5/2 valence strength. The experimental strength functions compare rather well with the predictions of the quasiparticle-phonon model.
