Alpha-gamma decay studies of ^247 Md

lpha decay and spontaneous fission of the ground-state and the isomeric state of ^247 Md were investigated with specific emphasis to identify the ground-state of the daughter nucleus ^243 Es. The decay studies were accompanied by measuring α - γ coincidences. On the basis of the measured data an improved decay scheme of ^247 Md is proposed. Spontaneous fission half-lives of ^247g Md and ^247m Md 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.
