摘要：
The decay of odd-mass mendelevium isotopes (A = 247-255) has been studied by means of alpha-gamma spectroscopy. Strong evidence for a small alpha branch in the decay of Md-253 was found. gamma lines in coincidence with alpha-decays of Md-247,Md- 249,Md- 251,Md- 253 have been observed for the first time. Levels in the einsteinium daughter nuclei were assigned on the basis of alpha-gamma coincidence measurements. An energy systematics of the 7/2(-)[514] Nilsson level could be established, showing a correlation with the deformation parameter beta(2) of the corresponding nuclei. The results are compared with theoretical predictions
