(American Physical Society, 2012-06)
Previously unknown states in 18Na and 19Mg have been studied by measuring the trajectories of their decay products with microstrip detectors. Analyzing angular correlations of the fragments provided information on decay ... -
Observation of narrow states in nuclei beyond the proton drip line: (15)F and (16)Ne
Mukha, I.; Timofeyuk, N.K.; Sümmerer, K.; Acosta Sánchez, Luis Armando; Álvarez, M. A. G.; García Ramos, José Enrique (American Physical Society, 2009-06)
Two high-lying states in 15F and 16Ne, unbound with respect to one-proton (1p) and two-proton (2p) emissions, have been observed in fragmentation of 17Ne at intermediate energies. They undergo mainly sequential emissions ... -
Observation of two-proton radioactivity of (19)Mg by tracking the decay products
Mukha, I.; Sümmerer, K.; Acosta Sánchez, Luis Armando; Álvarez, M. A. G.; García Ramos, José Enrique (American Physical Society, 2007-11-02)
We have observed the two-proton radioactivity of the previously unknown 19Mg ground-state by tracking the decay products in-°ight. For the ¯rst time, the trajectories of the 2p-decay products, 17Ne+p+p, have been measured ... -

Proton-proton correlations were observed for the two-proton decays of the ground states of 19Mg and 16Ne. The trajectories of the respective decay products, 17Ne+p+p and 14O+p+p, were mea- sured by using a tracking ... -

Sánchez Benítez, Ángel Miguel; Escrig, Diego; Álvarez, M. A. G.; Andrés, M. V.; Angulo, C.; García Borge, María José; García Ramos, José Enrique (Institute of Physics, 2005-09-12)
We have measured elastic cross sections of the scattering of 6He at ELab = 14, 16, 17, 18, 22 MeV on 208Pb in the angular ranges of 20± − 64± and 135± − 170±. A significant amount of 4He events is found at energies well ... -

Mukha, I.; Sümmerer, K.; Acosta Sánchez, Luis Armando; Álvarez, M. A. G.; García Ramos, José Enrique (American Physical Society, 2010-11-29)
A powerful method of investigating proton-unbound nuclear states by tracking their decay prod- ucts in °ight is discussed in details. To verify the method, four known levels in 15F, 16Ne, and 19Na were investigated by ... -
