The Mean

The gamma-ray spectrum after thermal neutron capture has been studied using a Ge(Li) pair spectrometer. Out of 140 transitions observed above 1.95 MeV, 3 have been tentatively assigned to 38Cl and the rest to 36Cl. An improved decay scheme is proposed for 36Cl which involves 43 levels. The Q value for the 35Cl(n,γ)36Cl reaction is estimated to be 8579.1 ± 0.5 keV and the multiplicity of the reaction found to be 2.5. A tentative estimate of the Q value for the 37Cl(n,γ)38Cl reaction yielded a result of 6107.4 ± 0.8 keV. The mean reduced widths for primary dipole transitions have been calculated and compared with theoretical estimates.

The Mean

The gamma-ray spectrum following thermal neutron capture in aluminum has been studied using a Ge(Li) pair spectrometer. A total of 143 transitions has been observed above 2.1 MeV, and most of these have been placed in a decay scheme. Some 51 levels in 28Al are observed to be populated in the reaction. The Q value for the 27Al(n,γ)28Al reaction is estimated to be 7725.4 ± 0.5 keV, and the multiplicity is found to be 2.0. The mean relative strengths of primary E1 and M1 transitions have been calculated and an attempt has been made to use these to determine the multipolarities of primary transitions leading to levels of unknown parity.

Gamma Coincidence

The 39K(n,γ)40K reaction has been studied using a Ge(Li) and a Ge(Li)–Ge(Li) spectrometer. A total of 252 gamma-ray transitions has been observed and a gamma–gamma coincidence matrix involving 62 transitions has been established. A decay scheme based on the experimental results is deduced for 202 of the observed gamma-ray transitions. Spins and parities of some excited states have been estimated from the deduced branching ratios. The neutron separation energies of the 40K and 42K nuclei have been determined as 7800.5 ± 0.2 and 7535.2 ± 1.5 keV respectively.
