8. Isobaric analog states of neutron-rich nuclei. Doppler shift as a measurement tool for resonance excitation functions.

Author

Gross, Carl J., Nazarewicz, Witold, Rykaczewski, Krzysztof P., Boutachkov, P., Rogachev, G. V., Goldberg, V. Z., Aprahamian, A., Becchetti, F. D., Bychowski, J. P., Chen, Y., Chubarian, G., DeYoung, P. A., Kolata, J. J., Lamm, L. O., Peaslee, G. F., Quinn, M., Skorodumov, B. B., and Wohr, A.

Abstract

We present a new approach for the measurement of resonance excitation functions of neutron-rich nuclei using Doppler shift information. Preliminary data from the first application of the method is presented in the spectroscopy studies of 7He isobaric analog states in 7Li. [ABSTRACT FROM AUTHOR]

9. Analog states of 7He observed via the 6He(p,n) reaction.

Abstract

Isobaric analog states of 7He have been investigated by a novel technique involving the observation of the resonant yield of neutrons from the 6He(p,n) reaction in coincidence with gamma rays from the decay of the (0(+),T=1) state in 6Li. The gamma rays provide a clean signature for the isospin-conserving neutron decay of the low-lying isobaric analog resonances. It is conclusively shown that the analog of the recently observed low-lying spin-orbit partner of the 7He ground state does not exist. Evidence is presented that this state lies at much higher energies, in agreement with microscopic calculations.
