Iacob, V. E.; Zhai, Y.; Al-Abdullah, T.; Fu, C.; Hardy, John C.; Nica, N.; Park, H. I.; Tabacaru, G.; Trache, L.; Tribble, Robert E. (American Physical Society, 2006)We present the first study of the beta decay of Al-23 undertaken with pure samples. The study was motivated by nuclear astrophysics questions. Pure samples of Al-23 were obtained from the momentum achromat recoil separator ...

Iacob, V. E.; Hardy, John C.; Gagliardi, Carl A.; Goodwin, J.; Nica, N.; Park, H. I.; Tabacaru, G.; Trache, L.; Tribble, Robert E.; Zhai, Y.; Towner, I. S. (American Physical Society, 2006)We have measured the beta-decay branching ratio for the transition from Na-21 to the first excited state of Ne-21. A recently published test of the standard model, which was based on a measurement of the beta-nu correlation ...

Nica, N.; Hardy, John C.; Iacob, V. E.; Goodwin, J.; Balonek, C.; Hernberg, M.; Nolan, J.; Trzhaskovskaya, M. B. (American Physical Society, 2009)We have measured the K-shell internal conversion coefficient, alpha(K), for the 346.5-keV M4 transition in (197)Pt to be 4.23(7). This result differs from a previous value, which disagreed significantly from theory. Our ...

Nica, N.; Hardy, John C.; Iacob, V. E.; Balonek, C.; Trzhaskovskaya, M. B. (American Physical Society, 2008)Recently we measured the ratio of K-shell internal conversion coefficients, alpha(K), for the 127.5-keV E3 transition in (134)Cs and the 661.7-keV M4 transition in (137)Ba. We here report a measurement of the 165.9-keV M1 ...

Goodwin, J. R.; Nica, N.; Iacob, V. E.; Dibidad, A.; Hardy, John C. (American Physical Society, 2010)We have measured the half-life of the beta(-) decay of (198)Au to be 2.6948(9)d, with the nuclide sited in an insulating environment. Comparing this result with the half-life we measured previously with a metallic environment, ...

Iacob, V. E.; Hardy, John C.; Golovko, V.; Goodwin, J.; Nica, N.; Park, H. I.; Trache, L.; Tribble, Robert E. (American Physical Society, 2008)The half-life of (10)C has been measured to be 19.310(4) s, a result with 0.02% precision, which is a factor of three improvement over the best previous result. Since (10)C is the lightest superallowed 0(+)-> 0(+) beta(+) ...

Iacob, V. E.; Hardy, John C.; Banu, A.; Chen, L.; Golovko, V. V.; Goodwin, J.; Horvat, V.; Nica, N.; Park, H. I.; Trache, L.; Tribble, Robert E. (American Physical Society, 2010)We measured the half-life of the superallowed 0(+) -> 0(+) beta(+) emitter (26)Si to be 2245.3(7) ms. We used pure sources of (26)Si and employed a high-efficiency gas counter, whichwas sensitive to positrons from both ...

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. ...

Nica, N.; Hardy, John C.; Iacob, VE; Raman, S.; Nestor, CW; Trzhaskovskaya, MB. (American Physical Society, 2004)The 10.5-day isomer in Ir-193 decays by a single 80.2-keV M4 transition directly to the ground state of that nucleus. We have measured the total intensity of K x rays relative to 80.2-keV gamma rays for this transition to ...

Nica, N.; Hardy, John C.; Iacob, VE; Montague, JR; Trzhaskovskaya, MB. (American Physical Society, 2005)We have measured the total intensity of K x rays relative to 129.4-keV gamma rays from decay of the second excited state in Ir-191. This (M1+E2) transition was observed following the beta decay of 15.4-d Os-191. Our measured ...

Nica, N.; Hardy, John C.; Iacob, V. E.; Rockwell, W. E.; Trzhaskovskaya, M. B. (American Physical Society, 2007)We have measured the ratio of K-shell internal conversion coefficients, alpha(K), for the 127.5-keV E3 transition in Cs-134 and the 661.7-keV M4 transition in Ba-137. Previous measurements of these alpha(K) values led to ...
