    Notizen: Summary Neurological manifestations were analysed in 13 patients with left atrial myxoma confirmed by histological study. In this group, 6 patients had neurological complaints at initial presentation, 5 had cardiac symptoms, and 4 patients presented with signs of systemic disease. CT was performed in 10 and MRI in 7 patients. There were signs of ischaemic or haemorrhagic infarction (6 of 12) and one lesion suggestive of myxoma metastasis; other findings mainly comprised non-specific white matter lesions revealed by MRI. Neurological follow-up 0.5–8 years after tumour resection revealed no delayed neurological complications, follow-up CT and MRI findings were not suggestive of lesions acquired after operation. It is suggested that this rare condition of cardiac myxoma should be suspected in young patients with CNS symptoms or signs lacking cerebrovascular or cardiovascular risk factors and should be included in the differential diagnosis of vasculitis. With timely diagnosis and resection of the cardiac tumour the long-term prognosis can be considered improved.

    Notizen: Abstract Superradiant transitions were observed between high lying levels in Sr. The transitions react very sensitively to an external electric field. Superradiant cascades or one transition in a superradiant branching can be suppressed. The square root of the high of a superradiant pulse decreases with the second power of the electric field strength. This behaviour can be explained by calculations.
