Cross sections for the 44Ti(alpha,p)47V reaction which significantly affects the yield of 44Ti in supernovae were measured in the energy range 5.7 MeV

The single-particle character of states outside the doubly magic (radioactive) nucleus 56 Ni has been determined through a measurement of the ͑d, p͒ neutron transfer reaction using inverse kinematics. From the spectroscopic factors of the low-lying states in 57 Ni, the astrophysically interesting yield for the 56 Ni͑p, g͒ reaction to the mirror nucleus 57 Cu has been calculated, utilizing charge symmetry. The rate for this reaction in the temperature range typical of novae, supernovae, and x-ray bursts is found to be more than 10 times higher than previously assumed. [S0031-9007 (97)05085-0]

Reactions with a heavy projectile incident on a light target can be used for the efficient in-flight production of secondary radioactive beams. An overview of this technique is given using data on 17 F beams produced via the p(17 O, 17 F)n and d(16 O, 17 F)n reactions. With primary 16,17 O beam currents of 100 pnA, intensities of up to 2ϫ10 6 17 F/s on target were achieved. Using this beam, the p(17 F,␣) 14 O reaction was measured.
