Dear BRAHMS'ers Our 'Man from Havana' has spotted the news below. Not so bad. Congrats to us all. cheers JJ _________________________________________________________________________ > Jens Jørgen Gaardhøje, Professor, Dr. Sc. > Niels Bohr Institute, Blegdamsvej 17, 2100 Copenhagen, Denmark. > Tlf: (+45) 35 32 53 09, secr.
