Gamma Decay

A method for estimating spins of highly excited nuclear states based on their gamma decay branching ratios is examined for sd and fp shell nuclei. Measures of similarity between emitting states have been made and a number of nuclei examined. Clear spin selectivity is observed in the spectrum similarities for resonant proton capture states in fp shell nuclei. In sd shell nuclei, the selectivity is weaker. The method of multidimensional scaling has been used to study the effect of spin on similarity using a large number of states of known spin in two test nuclei, 19F and 59Cu. Spin assignments are proposed for several resonances in 59Cu. Monte Carlo simulations were used to study factors influencing similarities and scaling configurations.

Existing Data

Excited states in 59Cu and 63Cu have been studied with radiative proton capture. Doppler shift attenuation factors have been measured for γ-rays depopulating these states, with ion recoil speeds of approximately 0.1% of the speed of light. Measurements of resonance strengths reported here, together with existing data from other techniques, have been used to deduce lifetimes for the same states. For five cases where the DSA factors and the lifetimes have been determined independently, consistency with DSAM theory is optimized when the standard energy loss value is multiplied by a factor of 0.94 ± 0.11.

Gamma Decay

The gamma decay of the resonance-like structures observed in the reaction of radiative capture of protons by the nuclei 22Ne, 26Mg, 30Si, 34,36S, and 38Ar in the region of excitation energies of 7…12 MeV was studied. The excitation functions of this reaction were measured. The resonance strengths in the energy range of the accelerated protons Ep = 1.0…3.0 MeV were determined. The obtained discrete distributions of the magnetic dipole γ-transitions on the ground and excited states for the nuclei of the 2s1d-shell have resonance character. Giant M1 resonance on the ground and excited states in the 23Na, 27Al, 31P, 35.37Cl, and 39K nuclei has been identified. The position of the M1 resonance on excited states coincides with that predicted by the Brink-Axel hypothesis for nuclei that are at the beginning of the subshell.
