Abstract

The two-proton radioactivity has been evidenced experimentally in 2002 in the ground-state decay of 45Fe, while this new decay mode was predicted since the 60's. The first observations have been done indirectly, from various global quantities measured in the decay process (half-file, Q-value, daughter decay,...). Since then, new devices have been developed in order to perform energy and angular measurements of the emitted particles. The comparison of full experimental observations with theoretical models opens a new access to nuclear structure a the drip-line. [ABSTRACT FROM AUTHOR]

9. β-delayed emission of protons at the proton drip-line: the cases of 43Cr and 51Ni.

Abstract

Studies of β-delayed emission of protons for 43Cr and 51Ni were performed with a Time Projection Chamber. This detection setup allows to reconstruct in the three-dimensional space the tracks of the protons emitted. For the first time, β-delayed emission of two protons is directly observed for 43Cr and 51Ni. The question about correlations between protons can be accessed. Finally, we show that 43Cr can emit up to three delayed protons. [ABSTRACT FROM AUTHOR]

Abstract

Two-proton radioactivity is an exotic decay mode for very proton-rich nuclei. It was observed experimentally for the first time in 2002 for the nucleus 45Fe but the two protons could not be directly detected. So a new detector has been developed, a Time Projection Chamber, to individually observe the two protons emitted. It was used successfully during two experiments for the study of 45Fe and 54Zn. Energy correlations have been studied and the relative angle between the two protons is calculated. [ABSTRACT FROM AUTHOR]

11. Spectroscopic studies of neutron-deficient light nuclei: decay properties of 21Mg, 25Si and 26P.

Abstract

Neutron-deficient nuclei with Tz equals to -3/2 and -2 have been produced at the GANIL/LISE3 facility in fragmentation reactions of a 95 MeV/u 36Ar primary beam in a 12C target. For the first time, β-delayed proton and β-γ emission has been simultaneously observed in the decay of 21Mg, 25Si and 26P. The decay scheme of the latter is proposed and the Gamow-Teller strength distribution in its β decay is compared to shell-model calculations based on the USD interaction. The B(GT) values derived from the absolute measurement of the β-branching ratios are in agreement with the quenching factor of about 60% obtained for allowed Gamow-Teller transitions in this mass region. A precise half-life of 43.7 (6) ms was determined for 26P, the β-2p emission of which was studied. The expected contribution of spectroscopic studies of neutron-rich nuclei is discussed with respect to the mirror asymmetry phenomenon occuring in analogous β decays. © 2003 American Institute of Physics [ABSTRACT FROM AUTHOR]
