Angular distributions have been measured at six 21Ne(p, γ)22Na analogue resonances, with Ep = 0.70, 0.77, 1.09, 1.21, 1.56 and 1.84 MeV, and at a candidate for analogue resonance with Ep = 1.11 MeV. Gamma-ray mixing ratios have been obtained for the first time for the decays of these levels with determination of spin-parity assignments. The spins and parities for the bound states at 1.98 and 4.36 MeV have been deduced. Transition strengths provide information on the isoscalar and isovector strengths in the self-conjugated nucleus 22Na.

The Doppler-shift attenuation (DSA) measurements of 7-rays performed on five S4Fe(p, Y ) ~~C O resonances yielded mean lifetimes of 20 levels in ''CO below 5.5MeV, seven of them for the first time. Angular distribution measurements were carried out on 17 j4Fe(p, 7 ) 5 5 C 0 resonances in the energy range E, = 1.1-2.3 MeV. The analysis of the angular distributions along with the present DSA and available literature data lead to the following unique spin and parity assignments for four bound states: 512-(E, = 2659 keV), 512-(37251,312-(4164) and 512' (4548). The spin of the 3563 keV state was found to be 3/2. The unique spin values of eight resonance states were determined. The present results are compared with recent shell-model calculations.
