Study of Gamma Rays from the ${Ca}^{43} (p, p^{'}, γ) {Ca}^{43}$ Reaction and the Decay of $K^{43}$ and ${Sc}^{43}$

A study has been made of the

γ

-ray spectra produced in the proton bombardment of

{Ca}^{43}

at proton energies of 2.550, 3.235, and 3.605 MeV.

γ

-ray branching ratios and excitation energies were determined for most states in

{Ca}^{43}

previously seen in decay-scheme and reaction studies up to an excitation energy of 2.25 MeV. An examination of the

γ

-ray spectrum following the radioactive decay of

{Sc}^{43}

shows that the

log ft

value for a transition to a possible

{\frac{9}{2}}^{-}

state below 1.5 MeV in

{Ca}^{43}

is greater than 5.7. Examination of the decay of

K^{43}

shows some discrepancies with previous work.
