Spin and isospin characteristics of the excited states of /sup 36/Ar through the reaction /sup 32/S(. cap alpha. ,. gamma. )/sup 36/Ar in the bombarding energy range E/sub. cap alpha. / = 4 to 5 MeV
The ..cap alpha.. capture reaction /sup 32/S(..cap alpha..,..gamma..)/sup 36/Ar was studied in the bombarding energy range of E/sub ..cap alpha../ = 4.13 to 5.00 MeV corresponding to the excitation energy range of E/sub x/ = 10.31 to 11.08 MeV in /sup 36/Ar. Seven resonances have been located and their resonance strengths determined. Two of the resonances decay predominantly to the ground state while the other five decay predominantly to the first excited state of /sup 36/Ar. Angular distribution measurements of the predominant decay gamma ray have been performed and the spin and parity of all the resonances assigned. The isospin of two of the resonances have been assigned as T = 0 while T = 1 has been assigned for three others. Evidence has been obtained for the operation of the isospin selection rule for the dipole (E1 and M1) and quadrupole (E2) gamma decay.
