Alpha-gamma decay studies of $^{247}$Md
Résumé
Alpha decay and spontaneous fission of the ground-state and the isomeric state of 247Md were investigated with specific emphasis to identify the ground-state of the daughter nucleus 243Es. The decay studies were accompanied by measuring α-γ coincidences. On the basis of the measured data an improved decay scheme of 247Md is proposed. Spontaneous fission half-lives of 247gMd and 247mMd were determined and the fission hindrance of the high spin ground-state (7/2−) relative to the low spin isomeric state (1/2−) was estimated.
