New levels in $^{19}\mathrm{F}$ with spins of ${\frac{9}{2}}^{+}$ and $\frac{11}{2}$ have been discovered at energies of 6592 \ifmmode\pm\else\textpm\fi{} 2 and 7937 \ifmmode\pm\else\textpm\fi{} 3 keV, respectively. It is suggested that these levels,

Thirteen new resonances in the 15N(α,γ)19F reaction have been discovered in the region Eα = 600–3150 keV. γ-Decay schemes and radiative yields are reported for several of them. Spins and parities for 10 levels in 19F are also reported.

The construction and operation of a monitoring ionization chamber are described. By its use, the delivery of successive X-ray exposure doses, normalised to the reading of the monitoring chamber, can be accomplished with a precision of better than 0·

The radiative width of the 6+ resonance at Eα = 5.06 MeV in the 16O(α, γ)20Ne reaction has been measured to be ωγ = 1.30 ± 0.20 eV corresponding to a transition strength of 20 ± 3 W.u. for the 6+ to 4+ transition in 20Ne. Comparison is made to

A weak resonance at 850 keV in 15N(α,γ)19F corresponding to a level at 4681 ± 1 keV in 19F has been found. Angular distributions and Doppler shifts have been measured for the primary decays to the 5/2− level at 1.35 MeV (63%), 3/2− level at 1.

The Canadian and U.S. standard free-air ionization chambers have been compared under identical conditions of X-ray tube kilovoltage and filtration. The comparison shows that the ratio of exposure dose-rate measurements differs from unity by about 0·

An analog method is described for computing the Gaussian integral transformation which arises in the problem of making resolution corrections. Only apparatus which is readily available has been used. The basic element is a photomultiplier which views

A resonance has been discovered in the 15 N (α,γ) 19 F reaction which strongly populates the recently-discovered [1] 13 + 2 level at 4.648 MeV in 19F. Measurements show that it corresponds to a level with spin 11 2 in 19F at EX = 6.500 MeV.

The two lowest T = 3 2 states in 19 F have been found as strong isolated resonances in the 15 N (α, γ) 19 F reaction. Some significant discrepancies are found between the measured transition strengths and those calculated from shell-model wave func
