| Abstract: | We have begun a program to test weak interaction symmetries by trapping in a Magneto-optic trap (MOT) isotopes produced at the TRIUMF cyclotron’s on-line separator TISOL. We are searching for non-Standard Model scalar contributions to the β+−ν correlation in the 0+→0+ Fermi decay of 38mK. We have trapped 38mK and 37K in a vapor-cell MOT, and transferred them to a second MOT which houses the nuclear detectors. The recoiling nuclei freely escape the trap and are detected in a microchannel plate; simultaneous detection of the β+ momentum allows reconstruction of the ν momentum. Approximately 500,000 β+ -recoil coincidences have been observed in June 1998; analysis is proceeding. |
