Abstract

The proton separation energy of

{}^{34}{Cl}

has been measured to be 5143.30(5) keV in a series of overlapping and self-consistent experiments involving the study of three resonances in the

{}^{33}S

(p,γ) reaction, using a variety of techniques in laboratories in Auckland and Florence. This figure is in disagreement with the only other published value. By combining the proton separation energy with the only measured value for the

{}^{34}S

neutron separation energy, the

Q_{e c}

for the

{}^{34}{Cl}

superallowed decay becomes 5491.48(12) keV. Some comments are offered on the associated

{}^{34}S

(p,n

)^{34}

Cl threshold energy measurement.
