    • Precise half-life measurements for the superallowed beta(+) emitters Ar-34 and Cl-34 
      Iacob, V. E.; Hardy, John C.; Brinkley, J. F.; Gagliardi, Carl A.; Mayes, V. E.; Nica, N.; Sanchez-Vega, M.; Tabacaru, G.; Trache, L.; Tribble, Robert E. (American Physical Society, 2006)
      To contribute meaningfully to any test of the unitarity of the Cabibbo-Kobayashi-Maskawa (CKM) matrix, the measured ft value of a superallowed 0(+)-> 0(+) beta(+) transition must be obtained to a precision of 0.1% or better. ...
    • Q(EC) values of the superallowed beta emitters (10)C, (34)Ar, (38)Ca, and (46)V 
      Eronen, T.; Gorelov, D.; Hakala, J.; Hardy, John C.; Jokinen, A.; Kankainen, A.; Moore, I. D.; Penttila, H.; Reponen, M.; Rissanen, J.; Saastamoinen, A.; Aysto, J. (American Physical Society, 2011)
      The Q(EC) values of the superallowed beta(+) emitters (10)C, (34)Ar, (38)Ca, and (46)V have been measured with the JYFLTRAP Penning-trap mass spectrometer to be 3648.12(8), 6061.83(8), 6612.12(7), and 7052.44(10) keV, ...
    • Radius of B-8 halo from the asymptotic normalization coefficient 
      Carstoiu, F.; Trache, L.; Gagliardi, Carl A.; Tribble, Robert E.; Mukhamedzhanov, AM. (American Physical Society, 2001)
      The experimental asymptotic normalization coefficient determined from peripheral transfer reactions is used to obtain the root-mean-square radius of the wave function for the loosely bound proton in SB. It is shown that ...
    • Stellar reaction rate for (22)Mg + p -> (23)Al from the asymptotic normalization coefficient in the mirror nuclear system (22)Ne + n -> (23)Ne 
      Al-Abdullah, T.; Carstoiu, F.; Chen, X.; Clark, H. L.; Fu, C.; Gagliardi, Carl A.; Lui, Y. -W; Mukhamedzhanov, A.; Tabacaru, G.; Tokimoto, Y.; Trache, L.; Tribble, Robert E. (American Physical Society, 2010)
      The production of (22)Na in ONe novae can be influenced by the (22)Mg(p,gamma)(23)Al reaction. To investigate this reaction rate at stellar energies, we have determined the asymptotic normalization coefficient (ANC) for ...
    • Structure of (23)Al from the one-proton breakup reaction and astrophysical implications 
      Banu, A.; Trache, L.; Carstoiu, F.; Achouri, N. L.; Bonaccorso, A.; Catford, W. N.; Chartier, M.; Dimmock, M.; Fernandez-Dominguez, B.; Freer, M.; Gaudefroy, L.; Horoi, M.; Labiche, M.; Laurent, B.; Lemmon, R. C.; Negoita, F.; Orr, N. A.; Paschalis, S.; Patterson, N.; Paul, E. S.; Petri, M.; Pietras, B.; Roeder, B. T.; Rotaru, F.; Roussel-Chomaz, P.; Simmons, E.; Thomas, J. S.; Tribble, Robert E. (American Physical Society, 2011)
      The ground state of the proton-rich nucleus (23)Al has been studied by one-proton removal on a carbon target at about 50 MeV/nucleon using the EXOGAM + SPEG experimental setup at GANIL. Longitudinal momentum distributions ...
