Abstract: | Excited Jπ=0+ states in 40Ca have been identified by the observation of L=0 angular distributions in the 38Ar(τ, n) 40Ca reaction. Strong transitions are observed to the ground state, the known 2p–2h at 9.38 (T=1) and 11.98 MeV (T=2), and to states at 8.28 and 10.65 MeV. The strongest excited-state transition is to the 8.28 MeV state, which we identify as the 2p–2h T=0 state. The Jπ=0+ state at 7.30 MeV which has been suggested as the 2p–2h T=0 state is not observed. |
