SQRT(S)=44 AND 62 GEV. COUNTER DATA FROM THE CERN ISR. THE CROSS- SECTION IS GIVEN AS A FUNCTION OF DIMUON MASS AT THE 2 ENERGIES. NOTE THAT THE CROSS SECTION AT SQRT(S)=62 DIFFERS SLIGHTLY FROM THAT LISTED IN THE EARLIER PAPER (PRL 45,863 - SC=ANTREASYAN 80). THAT CROSS-SECTION WAS OBTAINED FROM F.VANUCCI. THE CROSS SECTIONS IN THIS PAPER HAVE BEEN OBTAINED FROM J.A.PARADISO IN WHOSE THESIS THESE NUMBERS APPEAR. FURTHER DISTRIBUTIONS AT SQRT(S)=62 APPEAR IN PRL 47,12 (1981). ; Other ; No description provided.
