Precision mass measurements of 67Fe and 69,70Co: Nuclear structure toward N = 40 and impact on r-process reaction rates

Autor: Canete, L., Giraud, S., Kankainen, A., Bastin, B., Nowacki, F., Poves, A., Ascher, P., Eronen, T., Alcindor, V., Jokinen, A., Khanam, A., Moore, I. D., Nesterenko, D. A., De Oliveira Santos, F., Penttilä, H., Petrone, C., Pohjalainen, I., de Roubin, A., Rubchenya, V. A., Vilen, M., Äystö, J.

Accurate mass measurements of neutron-rich iron and cobalt isotopes 67Fe and 69,70Co have been realized with the JYFLTRAP double Penning-trap mass spectrometer. With novel ion-manipulation techniques, the masses of the 69,70Co ground states and the 1

Detailed spectroscopy of the neutron-unbound nucleus F28 has been performed for the first time following proton/neutron removal from Ne29/F29 beams at energies around 230 MeV/nucleon. The invariant- mass spectra were reconstructed for both the F(*)27

Precision mass measurements on neutron-rich rare-earth isotopes at JYFLTRAP - reduced neutron pairing and implications for the $r$-process calculations

The rare-earth peak in the $r$-process abundance pattern depends sensitively on both the astrophysical conditions and subtle changes in nuclear structure in the region. This work takes an important step elucidating the nuclear structure and reducing
