Dear colleagues, 

 

I am a physics universitary teacher working in a little university in 
Brazil's inner countryside.

I have developed some research works on iron-cobalt based magnetic alloys ( 
references below), with the cooperation of Dr. A.I.C.Persiano and 
Dr.J.D.Ardisson, researchers respectively from the Physics Department of UFMG 
and Applied Physics Laboratory of CDTN-MG, both institutes located in Belo 
Horizonte, MG, 200 km far away from the city where I am nowadays working. 

Unfortunately my department has not yet the complete laboratorial condition 
in order to perform experimental works on materials sciences and so I am 
seeing myself in a vicious circle: I am not able to develop experimental 
works in a continuous way, I can not to orient Master and Doctorate students 
and so I have not a scientific production that permits me to compete for 
financial support from governmental agencies.  Well, for those reasons I am 
requesting your help. I think that is possible to exist among the Mössbauer 
community some laboratory  that  could to endow me a  Mössbauer Spectrometer. 
The technological advances certainly has produced some obsolete setup and I 
will be glad to receive one in order to begin a Mossbauer Laboratory im my 
university. 

Thanks in advance for your attention.
