High-precision half-life measurements of the T=1/2 mirror β decays F17 and Cl33 / Grinyer, J (GANIL) ; Grinyer, G F (GANIL) ; Babo, M (GANIL) ; Bouzomita, H (GANIL) ; Chauveau, P (GANIL) ; Delahaye, P (GANIL) ; Dubois, M (GANIL) ; Frigot, R (GANIL) ; Jardin, P (GANIL) ; Leboucher, C (GANIL) et al.
Background: Measurements of the ft values for T=1/2 mirror β+ decays offer a method to test the conserved vector current hypothesis and to determine Vud, the up-down matrix element of the Cabibbo-Kobayashi-Maskawa matrix. In most mirror decays used for these tests, uncertainties in the ft values are dominated by the uncertainties in the half-lives. [...]

High-precision half-life measurement for the isospin T=1/2 mirror β+ decay of $^{21}$Na / Grinyer, J (GANIL) ; Grinyer, G F (GANIL) ; Babo, M (GANIL) ; Bouzomita, H (GANIL) ; Chauveau, P (GANIL) ; Delahaye, P (GANIL) ; Dubois, M (GANIL) ; Frigot, R (GANIL) ; Jardin, P (GANIL) ; Leboucher, C (GANIL) et al.
The half-life of the isospin T=1/2 mirror β+ decay of Na21 was measured at the GANIL-SPIRAL radioactive ion beam facility to be T1/2=22.422 (10) s, a result that is more than a factor of 5 times more precise than the previous world average, with a resulting ft value that is now two times more precise. The precision of this new result implies that the half-life is no longer the dominant source of uncertainty in the Ft value used in the calculation of Vud from mirror decays to test the conserved vector current hypothesis of the standard model.

Nuclear spectroscopy with an on-line time-of-flight mass- identification system : Heavy T=1/2 mirror nuclei / Edmiston, M D (Michigan State U.) ; Warner, R A (Michigan State U.) ; McHarris, W C (Michigan State U.) ; Kelly, W H (Michigan State U.)
The construction and use of an on-line He-jet fed time-of-flight mass- identification system are described. Using this system the f/sub 7/2/ T=/sup 1///sub 2/ nuclide /sup 47/Cr has been produced and identified. [...]
