PT Journal AU Broda, Rea Gadea, A TI Proton-hole states in the N=30 neutron-rich isotope K-49 SO Physical Review C JI Phys. Rev. C PY 2010 BP 034319 EP 7pp VL 82 IS 3 DI 10.1103/PhysRevC.82.034319 LA English AB Excited states in the N = 30 neutron-rich isotope K-49 have been studied using multinucleon transfer reactions with thin targets and the PRISMA-CLARA spectrometer combined with thick-target gamma-coincidence data from Gammasphere. The d(3/2) proton-hole state is located 92 keV above the s(1/2) ground state, and the proton-particle f(7/2) state is suggested at 2104 keV. Three other levels are established as involving the coupling to 2(+) of two neutrons above the N = 28 shell. The measured or estimated lifetimes served to reinforce the interpretation of the observed level structure, which is found to be in satisfactory agreement with shell-model calculations. ER
