Measurements of the (3He, n) reaction have been carried out on targets of 78, 80, 82, 83, 84Kr at an incident energy of 25.4 MeV. Angular distributions were measured over the angular range 0°–22°, permitting the identification of L = 0 and some L = 2 transitions. Transitions to excited 0+ states were observed in all final nuclei except 82Sr. The results for L = 0 transitions have been compared with predictions of a model calculation assuming a pure pairing interaction. In 80Sr, a strong L = 0 transition to a state at 1 MeV excitation supports the suggestion of coexisting spherical and deformed states in this mass region. The Q-value for the 78Kr(3He, n)80Sr(g.s.) reaction has been measured as 2.99±0.03 MeV, yielding a value 79.924551±0.000032 a.m.u. for the 80Sr ground state.
