摘要：

The relative production yields and transverse mass spectra for Lambda,<(Lambda)over bar>,E(-) and (E) over bar(+) hyperons in proton-tungsten interactions are presented and compared with the WA85 results from central sulphur-tungsten interactions. A study of the negative particle yield has also bean undertaken and the ratio of Lambda hyperons to negative particles has been calculated.
