Descriptions
The structure of the nuclear quadrupole resonance line in a single crystal of iodine has been studies and it was found that the line was into five lines at least.
The patterns of the resonance lines in the powder of iodine and in the mixture of iodine and sulfer or paraffin have also been reported.
In this paper, the changes of the resonance lines by irradiation with gamma-rays from cobalt-60 was investigated.
After irradiation at an integral does of 1.3 × <10>^5 roentgen, the change of resonance frequency was not found, and the patterns of the resonance lines in the mixtuers were not also changed, but in the single crystal, the resolved lines were vanished and the pattern was changed into the shape of line in the powder. This shows that the structure of a single crystal of iodine was effected some changes by the irradiation of about <10>^5 roentgen.
