High-Lying Proton Strengths Observed in Stripping Reactions

Strong transitions to high-lying proton states are observed for the first time in the study of the (..cap alpha..,t) and (/sup 3/He,d) reactions on /sup 144/Sm at 80- and 240-MeV incident energy, respectively. The excitation energies, angular distributions, and strengths of these states suggest that...

Zusammenfassung:	Strong transitions to high-lying proton states are observed for the first time in the study of the (..cap alpha..,t) and (/sup 3/He,d) reactions on /sup 144/Sm at 80- and 240-MeV incident energy, respectively. The excitation energies, angular distributions, and strengths of these states suggest that they arise from proton stripping to high-spin outer subshells, e.g., 1h/sub 9/2/ and 1i/sub 13/2/.
