NONMESONIC DECAY OF Λ - HYPERON IN HEAVY HYPERNUCLEIL.Jarczyk 1 , B.Kamys 1 , P.Kulessa 1,2 , K.Pysz 1,2 , Z.Rudy 1 , A.Strzałkowski 1 , I.Zychor 31 M. Smoluchowski Institute of Physics, Jagiellonian University, Kraków2 H. Niewodniczański Institute of Nuclear Physics PAN, Kraków3 A. Sołtan Institute for Nuclear Studies, WarszawaExperimental facility: Cooler Synchrotron COSY, Forschungszentrum JuelichThe nonmesonic Λ-decay Λ+N → N+Nrepresents an example for the nonleptonic weakinteraction of baryons with a change ofstrangeness (∆S = 1) and isospin (∆I = 1/2 or 3/2).The study of the nonmesonic decay, whichproceeds via a weak interaction only (theCoulomb and strong interactions preserve thestrangeness) allows to study both parity violatingand parity conserving amplitudes in contrast toe.g. the nucleon-nucleon weak interaction, wherethe latter amplitudes are completely masked bystrong and Coulomb forces. The only possibilityto study nonmesonic decay of Λ-hyperon isinvestigation of hypernuclei since at presentneither beams nor targets of hyperons areavailable. Heavy hypernuclei are favorized forthis purpose, because another mode of the Λ-hyperon decay, i.e. Λ→π+N, which dominatesdecay of free hyperons is strongly Pauli blockedfor all but the lightest hypernuclei. We report hereon the investigations of production and decay ofheavy hypernuclei in proton interaction with Au,Bi, and U targets [1-9]. The experiments havebeen performed on the internal beam of COSYaccelerator in Forschungszentrum Juelich usingproton beams of two energies: 1 GeV, which isbelow the threshold for Λ-hyperon production,and 1.5 or 1.9 GeV at which hyperons can beproduced. The thin targets of Au, Bi or U(thickness of order of 30 µg/cm 2 ) with thin carbonbacking [5] , placed in the circulating beam ofCOSY accelerator were bombarded with 1 GeVand 1.5 (1.9) GeV protons in the subsequentacceleration cycles. This allowed for backgroundmeasurement (at 1 GeV) and hypernucleusproduction (at higher energies ) under identicaltarget conditions. The recoil shadow metod hasbeen applied for measurement of lifetime ofheavy hypernuclei produced in p+Bi [4], p+Au [7]and p+U [8] reactions. Details of the experimentalsetup and procedure are described in Ref. [5]whereas properties of the produced hypernucleiand the probability of their production and decaywere subject of theoretical estimations in Refs.[1,2]. The following lifetimes of the Λ-hyperonhave been obtained in the reported investigations:130±20 ps (Au target), 161±16 ps (Bi target) and138±18 ps (U target) giving the average value ofthe lifetime of Λ-hyperon in heavy hypernuclei145±11 ps, in excellent agreement with results ofstudies performed with antiprotons on Bi and Utargets ( Phys.Rev. C47, 1957 (1993) ) , i.e. 143±36ps, however, much more accurate. The lifetimesobtained from electron induced production ofheavy hypernuclei on Bi and U targets ( Sov. J.Nucl. Phys 43, 856 (1986); 46, 769 (1987) ) areorder of magnitude larger. Our experiments cangive estimation on cross section of such longliving hypernuclei to be smaller than 80nanobarns whereas cross section for production ofhypernuclei with lifetime of about 145 ps wasfound to be ~ 350 microbarns.In summary, the performed experiments havelead to the most precise value of the lifetime of Λ -hyperons in very heavy nuclei known up to now.Fig.1. The lifetimes of proton- and antiproton-produced hypernucleion Au, Bi and U targets. The horizontal bars present the statisticaland systematic errors added in quadrature. The position and width ofthe yellow vertical bar display the overall average value for thelifetime and its error, respectively. The smooth curve was evaluatedadding Gaussian curves representing results from individualexperiments.175
