Levels in 113115In as seen by the coulomb excitation and (HI,xn) reactions

For the Coulomb excitation measurements, four types of experiments were performed. First, using beams of 9.4-, 10-, and 10.6-MeV 4He ions, γ-ray yields were taken with an angle between the beam and the detector, theta, of 550. With these data one can confirm existing level diagrams, look for new transitions, and measure B(E2)'s and branching ratios. Secondly, γ-γ coincidence measurements were performed with a 10.6-MeV 4He beam to confirm the level diagrams and search for new transitions. Next, angular distributions were taken for a 10-MeV 4He ion beam to determine spins, parities and mixing ratios. Finally, a beam of 16O ions was used to determine the lifetimes of states whose decaying γ rays showed Doppler broadening. For the 110Pd(6Li,3n)113In measurements, two types of experiments were performed, both with a 24-MeV 6Li beam. First γ-γ coincidences were performed to find new transitions feeding those states previously known. Next, angular distributions were performed to confirm old spin assignments and to establish a basis for assignments to new levels observed. The results of the Coulomb excitation studies were that 113In is structurally very similar to 115In. Both nuclei can, to first order, be described by using an intermediate coupling strength in a weak coupling model. A firm experimental basis for spin and parity assignments to all levels except one (1630 keV in 113In) was established. In the (HI,xn) studies, levels which are candidates for higher lying core-coupled states were observed. Additionally, a strongly populated cascade was observed which is a good candidate (but not definitely confirmed) for the deformed rotational band. Finally, a very puzzling cascade of low energy (approximately 200-keV) γ rays was observed to feed a level at 2.2 MeV
