Report

Ortho-para transition rate in $\mu$-molecular hydrogen and the proton's induced pseudoscalar coupling $g_p$

Autor: Clark, J. H. D., Armstrong, D. S., Gorringe, T. P., Hasinoff, M. D., King, P. M., Stocki, T. J., Tripathi, S., Wright, D. H., Zolnierczuk, P. A.

Publikováno v: Phys.Rev.Lett. 96 (2006) 073401

We report a measurement of the ortho-para transition rate in the p$\mu$p molecule. The experiment was conducted at TRIUMF via the measurement of the time dependence of the 5.2 MeV neutrons from muon capture in liquid hydrogen. The measurement yielded

Scalar interaction limits from the beta-neutrino correlation of trapped radioactive atoms

Publikováno v: Phys.Rev.Lett. 94 (2005) 142501

We have set limits on contributions of scalar interactions to nuclear beta decay. A magneto-optical trap (MOT) provides a localized source of atoms suspended in space, so the low-energy recoiling nuclei can freely escape and be detected in coincidenc

Recoil alignment in muon capture on nitrogen-14

Autor: Gorringe, T. P., Corbin, D. P., Stocki, T. J.

Publikováno v: Phys.Rev. C71 (2005) 035503

We report a measurement of the longitudinal alignment $A_L$ of the recoil nucleus in the $\mu^- + ^{14}$N$(1^+, 0)$ $\to$ $\nu_{\mu} + ^{14}$C$(2^+, 7012)$ transition. The experiment was performed on the M9B beamline at the TRIUMF cyclotron via the m

Muon capture on Chlorine-35

Autor: Arole, S., Armstrong, D. S., Gorringe, T. P., Hasinoff, M. D., Kovash, M. A., Kuzmin, V., Moftah, B. A., Sedlar, R., Stocki, T. J., Tetereva, T.

We report measurements of $\gamma$--ray spectra from muon capture on $^{35}$Cl. For the allowed Gamow--Teller transitions to the $^{35}$S$(2939, 3/2^+)$ state and the $^{35}$S$(3421, 5/2^+)$ state we obtained their capture rates, hyperfine dependence

Gamma-rays from Muon Capture in $^{14}$N

Autor: Stocki, T. J., Measday, D. F., Gete, E., Saliba, M. A., Moftah, B. A., Gorringe, T. P.

Many new $\gamma$-rays have been observed, following muon capture on $^{14}$N. One had been reported before, and the low yield is confirmed, indicating that the nuclear structure of $^{14}$N is still not understood. Gamma-rays from $^{13}$C resulting

Report

The hyperfine transition in light muonic atoms of odd Z

Autor: Stocki, T. J., Measday, D. F., Gete, E., Saliba, M. A., Lange, J., Gorringe, T. P.

The hyperfine (hf) transition rates for muonic atoms have been re-measured for select light nuclei, using neutron detectors to evaluate the time dependence of muon capture. For $^{19}$F $\Lambda$$_{h}$ = 5.6 (2) $\mu$s$^{-1}$ for the hf transition ra
